The record m130 clamp heads set allows tradespeople to create a custom bar clamp of any required length using a standard piece of timber 1 inch thick. Ideal for workshops where extended clamping lengths are needed, this versatile system offers flexibility that fixed length clamps cannot match. The cast iron head and slides feature large thrust surfaces that distribute clamping pressure evenly across the workpiece, reducing the risk of damage to materials. This robust construction ensures reliable performance even under substantial loads, making the system suitable for furniture making, joinery, and general workshop clamping applications. The high quality steel handle and screw provide smooth, controlled adjustment and secure clamping action. A pin is conveniently attached by a welded chain to prevent loss during use, ensuring all essential components remain together when changing timber bars or storing the clamp heads between jobs.
