Zverák KWB 928320 zinková zliatina 50 × 200 mm

KWB 928320 is a bar clamp with a zinc die-cast body and clamping capacity of 50 × 200 mm, designed to secure workpieces during gluing, assembly and light carpentry tasks. The clamp combines a compact footprint with reliable pressure distribution, offering corrosion resistance from the zinc construction and a robust sliding mechanism for repeatable positioning. It is intended for workshop and DIY use where moderate clamping force and precise alignment are required.

Advantages

The zinc die-cast body provides improved corrosion resistance and dimensional stability compared with basic steel frames, while the 50 × 200 mm capacity suits small to medium tasks. The sliding bar and quick-adjust mechanism allow fast setup and positioning along the beam, and the clamp jaw design distributes pressure evenly to minimise marring of the workpiece. Its compact size and straightforward single-handed operation make it practical for bench work, fixtures and temporary holds during glue curing.

How to use

Position the clamp so that the fixed jaw bears against one side of the workpiece and slide the adjustable jaw along the bar until it contacts the opposite side. Use the quick-adjust mechanism to bring the jaws close, then tighten to the required pressure while ensuring even contact across the clamped surfaces. Keep the clamp perpendicular to the joint or surface to avoid uneven force; if necessary, use protective pads between the jaw and the workpiece to prevent marks. Release by loosening the adjustable jaw and sliding it away from the workpiece.

Recommendations

For consistent results, check the clamp for smooth sliding action and clean any debris from the bar before use. Do not exceed moderate force beyond the clamp’s intended capacity and avoid exposure to prolonged moisture despite the zinc construction — store in a dry place when not in use.
