Setting door frames is effortless with this set of 3 frame clamps. This is because the frame clamps allow you to press the door frames into the exact position and fix them in place. This means you still have both hands free and nothing can slip. It often happens that the door frame is compressed after foaming. This problem is avoided with the frame clamps. With these practical helpers, the desired tension is set and maintained using a handle and an infinitely variable pump system. The frame clamps consist of a three-part telescopic rod made of A3 steel with a spring and two plastic pressure plates. The pressure plates can be tilted up to an angle of 45° as they have ball joints. This makes it possible to insert door spreaders at an angle. The frame clamps are ready for use in just a few simple steps. Thanks to their telescopic design, the clamps can be adjusted to a length of 51 to 115 cm. The frame clamps are designed for a load capacity of 30 kg. If the pressure plate is tilted, the load capacity is reduced to 25 kg.
