Brüder Mannesmann tensor de cinta sin fin M911, cinta de nailon de 4 m, 4 esquineras, negro/naranja

When assembling a picture frame or gluing up a chair, keeping the corners tight and square is the difference between a clean joint and a frustrating redo. The Brüder Mannesmann M911 endless band clamp solves this with a 4-metre nylon strap that wraps around the entire workpiece and pulls evenly from four corner jaws. The screw-driven mechanism lets you apply pressure gradually, so you can feel the joint close without crushing the wood. The strap is wide and flexible, conforming to round or irregular shapes that rigid bar clamps cannot handle.

Why choose it

The four corner jaws distribute clamping force evenly, preventing racking and keeping mitred corners perfectly aligned.

The nylon band is gentle on finished surfaces and can be wiped clean after glue-ups. A quick-release lever lets you loosen the strap instantly once the glue has set.
