Installation Notes

Bar clamps require no tools for basic setup — position the jaw, slide the rail, and apply pressure via the drive mechanism. Avoid over-tightening on soft or finished materials to prevent surface damage or workpiece deformation. Inspect the rail and jaw mechanism before each use and keep contact surfaces clean for consistent clamping force.
