This comprehensive range of stainless steel universal clamps, power clamps, European retainers, square-mouth fixators, and side rail extenders forms the essential mounting backbone of the modern operating room — the critical interface components that connect every surgical positioning accessory, instrument holder, and auxiliary support to the operating table's side rail. Fabricated from 304 stainless steel for corrosion resistance, structural rigidity, and full autoclave compatibility, each clamp and retainer is precision-engineered to deliver reliable, repeatable locking strength that has been proven across thousands of surgical cases.
The product family covers round-hole clamps in multiple diameters — 16 mm, 19 mm, and 20 mm — to accommodate the full range of mounting rod sizes used by positioning accessories worldwide, as well as 25 mm square-mouth fixators for square-tube instruments and supports. Clamp plate dimensions span from 25 × 10 mm to 30 × 10 mm, ensuring a precise fit on the side-rail profiles of every major operating table brand. A dedicated line of side rail extenders allows additional accessories to be mounted beyond the table's factory rail length, expanding the table's usable mounting area without permanent modification.
Whether the surgical team needs to attach an auxiliary support arm, secure an instrument holder, fix a round rod or square tube to the rail, or extend the rail itself to accommodate more accessories, this clamp range provides the correct variant for every mounting requirement — delivering the stable, vibration-free, load-rated connection that patient safety and surgical precision demand.
Key Features & Clinical Advantages
304 stainless steel construction — Every clamp, retainer, and extender is fabricated from medical-grade 304 stainless steel that resists corrosion from repeated disinfection, maintains structural integrity under sustained and dynamic loads, and withstands standard autoclave sterilization cycles without deformation or surface degradation.
Multiple round-hole diameters — The range offers round-hole clamps in 16 mm, 19 mm, and 20 mm diameters, covering the standard mounting rod sizes used by the vast majority of surgical positioning accessories — from lightweight instrument holders to heavy-duty shoulder frames and leg supports.
Multiple clamp plate sizes — Clamp plates are available in 25 × 10 mm, 28.5 × 9.5 mm, 30 × 8 mm, and 30 × 10 mm dimensions, matching the side-rail profiles of all major operating table manufacturers and ensuring a secure, rattle-free fit without shims or adapters.
Square-mouth fixator option — The 25 mm square-mouth fixators provide positive anti-rotational engagement for square-tube instruments and supports, preventing unwanted rotation under load — essential for accessories that must maintain precise angular orientation throughout the procedure.
Side rail extender system — Stainless steel side rail extenders bolt onto the existing rail to increase the table's usable mounting length, allowing additional accessories to be installed beyond the factory rail endpoint — a cost-effective alternative to replacing the entire table when procedural requirements expand.
Proven locking strength — The clamping mechanism has been validated across thousands of surgical cases, delivering consistent, reliable holding force that prevents accessory migration, slippage, or rotation under the dynamic loads of surgical positioning — including steep Trendelenburg, lateral decubitus, and prone positions.
Rapid tool-free installation — All clamps feature knob-actuated or lever-actuated tightening mechanisms that allow surgical staff to install, adjust, and remove accessories in seconds without tools, streamlining case setup and turnover.
Model Variants & Specifications
Power Clamps
FP-039-B3 / FP-039-B4 — Power Clamp / Universal Clamp
Heavy-duty power clamps with clamp plates sized 30 × 8 mm (FP-039-B3) and 30 × 10 mm (FP-039-B4), each featuring a 16 mm round hole for mounting rods and auxiliary instruments. The power clamp design provides enhanced clamping force compared to standard universal clamps, making it the preferred choice for securing heavier accessories — including auxiliary support arms, instrument trays, and equipment mounts — that are subject to significant gravitational and lateral loads during the procedure. The 30 mm plate width provides broad contact with the side rail, distributing the clamping force evenly and preventing rail surface damage even when tightened to maximum holding force. The two plate-depth variants (8 mm and 10 mm) ensure compatibility with both narrow and standard side-rail profiles.
Universal Clamps — 19 mm Round Hole
FP-040-A1 / FP-040-A2 / FP-040-A3 / FP-040-A4 — Universal Clamp (Standard Rail Sizes)
A family of four universal clamps with clamp plates sized 28.5 × 9.5 mm (FP-040-A1), 25 × 10 mm (FP-040-A2), 30 × 8 mm (FP-040-A3), and 30 × 10 mm (FP-040-A4), each featuring a 19 mm round hole. The 19 mm diameter is the most widely used mounting rod size across the surgical positioning accessory industry, making this series the most versatile and frequently specified clamp in the range. The four plate-size variants ensure a precise match to the side-rail profile of virtually any operating table brand, while the standardized 19 mm opening accepts the full range of 19 mm rod accessories — including arm boards, hand rests, retractors, camera supports, and positioning frames.
FP-040-B2 / FP-040-B3 / FP-040-B4 — Universal Clamp (Extended Range)
Additional universal clamp variants in the FP-040 series, expanding the plate-size options to cover further rail profiles and ensure complete compatibility across the full spectrum of operating table brands. Each variant maintains the same 19 mm round hole diameter and the same proven clamping mechanism as the FP-040-A series, providing identical performance and reliability with a different plate geometry to match specific table rail dimensions.
FP-041-A1 — Universal Clamp (Universal Application)
A universal clamp with a 19 mm round hole designed for broad, cross-brand compatibility — applicable to any brand of side rail without requiring a specific plate-size match. This model is specified when the exact rail dimensions of the operating table are unknown or when a single clamp type must serve across a mixed fleet of tables from multiple manufacturers. The clamp's adjustable jaw mechanism accommodates minor variations in rail width and depth, providing a secure fit without the need to stock multiple plate-size variants.
Universal Clamps — 20 mm and 16 mm Round Holes
FP-042-A2 / FP-042-A3 — Universal Clamp
Universal clamps with round-hole diameters of 20 mm (FP-042-A2) and 16 mm (FP-042-A3), designed for accessories that use non-standard mounting rod sizes. The 20 mm hole accommodates heavier-duty rods used by certain positioning frames and support arms, while the 16 mm hole matches the smaller-diameter rods found on lightweight instrument holders, drip stands, and accessory mounts. These two variants extend the clamp range's compatibility to cover the full spectrum of rod diameters used across the surgical accessory ecosystem.
European Retainer
FP-042-B2 — European Retainer
A specialized retainer with a 25 × 10 mm clamp plate and a 19 mm round hole, designed to meet the mounting standards commonly specified in European operating room environments. The European retainer format is compatible with positioning accessories manufactured to European dimensional standards, ensuring that facilities sourcing accessories from European suppliers can achieve a precise, secure fit on their operating table side rails without modification. The 25 × 10 mm plate provides reliable grip on standard-width side rails, while the 19 mm round hole accepts the most common European-standard mounting rod diameter.
Square-Mouth Fixators
FP-042-C1 / FP-042-C2 / FP-042-D1 — Universal Square Mouth Fixator
A family of three square-mouth fixators, each featuring a 25 mm square opening designed to fit square tubes and square-profile instruments on the operating table side rail. Unlike round-hole clamps that allow the mounted rod to rotate freely within the opening, the square-mouth fixator provides positive anti-rotational engagement — locking the square tube in a fixed angular orientation that cannot shift under load. This is essential for accessories that must maintain a precise rotational position throughout the procedure, such as fixed-angle retractors, rigid camera mounts, and structural support frames where any rotation would compromise the surgical setup. The three variants (C1, C2, D1) offer different clamp plate configurations to match different side-rail profiles while maintaining the standardized 25 mm square opening.
Side Rail Extenders
FP-040-C1 / FP-040-C2 / FP-040-C3 — Side Rail Extender
A set of stainless steel side rail extenders that bolt directly onto the existing operating table side rail to increase its usable mounting length. When the surgical procedure requires more accessories than the factory rail length can accommodate — for example, when a shoulder frame, waist frame, leg frame, and multiple instrument holders must all be mounted simultaneously — the side rail extender provides the additional rail real estate needed without replacing the entire table. The three variants (C1, C2, C3) offer different extension lengths and mounting configurations to match different table brands and rail profiles. The stainless steel construction ensures the extender matches the durability and corrosion resistance of the original rail, and the bolt-on installation is fully reversible — leaving no permanent modification to the table.
