Malco 55110 Locking C-clamp Swivel Pads 11 Inches

Product Description

The MALCO 55110 is an 11-inch locking C-clamp with swivel pads, built for sheet metal fabrication, HVAC ductwork assembly, and general trade clamping tasks. Constructed from heat-treated alloy steel, it delivers high clamping force across a maximum clamping range of 3.38 inches. The swivel pads conform to tapered and irregular work surfaces, distributing force evenly to reduce surface marring. A patented Power Ring reinforces thread strength for long-term durability under repeated use. The hardened adjustment knob features an exclusive lubricity coating for smooth, consistent operation. This clamp is designed and manufactured in the United States.

The 55110 is suited for HVAC installers, sheet metal workers, plumbers, and general tradespeople who need reliable clamping during fabrication or assembly. The spacious jaw opening accommodates a variety of material thicknesses and shapes, making it practical for both bench work and field installations. The adjustment screw accepts a 5/16-inch hex key, allowing pressure adjustments in tight spaces where hand-turning the knob is not practical.

Installation Notes

This clamp is a hand tool and does not require electrical isolation or system shutdown before use. Inspect the swivel pads and adjustment screw threads before each use to confirm they are free of debris and damage. Do not exceed the rated clamping range, as overextension can reduce thread engagement and compromise holding force. A 5/16-inch hex key is required to adjust clamping pressure when the knob cannot be turned by hand.
