Bosch Professional FSN KZW Clamps

Work well but are very expensive. Usual problem, if you want/need these there are not a lot of options. On a more positive note, clamps work well, holding the rails tight. Usual Bosch quality should last a lifetime. Easy to operate, if cutting at an angle it is possible to take off part of the clamp! Glad I have these in my kit, just wish they were out so costly.

Took delivery of these yesterday, build quality is good, very solid construction! I haven't used them yet but they are purpose built and appear to be well designed! Pricey but worth it! They may look flimsy in the images, but they're not!! 10/19: Worked a treat, excellent piece of kit! Well worth the money!

If you have a FSN rail compatible saw there is not much choice regarding clamping. You either buy these or rely on friction. The item IS good at what it does, but it is clearly just a 3rd party Chinese made clamp with a Bosch spec adapter on the top for sliding into the rails. Therefore I have to say the item is over priced. However it IS good at what it does. I feel £30 would be a much more reasonable price for these clamps.

When I first seen these clamps I thought they were overpriced and small. When I saw them advertised on Black Friday deals I thought I would give them a try . When they arrived I was pleasantly surprised.. They are a good size good weight and good quality. Glad I bought them.

I know these are made to be compatible with the Bosch guide rail system but they do a damn good job of holding the rail to the workpiece. With a very easy trigger action to clamp down.

Quite expensive compared too other brands but this is the only one that works with Bosch guide rails very secure when clamped very well made and should last until I loose them

While they are a well made product do they really need to cost so much ??

Great match for the Bosch rails - holds them well. However, very expensive for what they are, given the price of similar clamps that would hold the top of the rail.

Good stuff

A must have for my FSN 1600 guide rail

Si usas una guía fsn son imprescindibles. Son un poco caros pero merecen la pena.

Pas toujours utilisables mais la règle guide se maintient bien sur de nombreuses surfaces

Bij het gebruik van de geleiderail van Bosch zijn deze twee klemmen eigenlijk onmisbaar. Veel handiger dan losse lijmklemmen. Maar voor twee van deze klemmen is 50 euro wel veel geld.
