Frame Struts Set of 3, Extendable 51-115cm, 30kg Carrying Capacity

With this set of 3 door frame struts, door frames can be built in effortlessly. This is because the frame struts allow to be pressed into the door frames, positioning them in the exact spot and fixing them in place. Both hands are free and nothing can slip. Sometimes it can happen that door frames break as they are compressed after placing the foam. This problem is avoided with the struts. The desired tension is set and maintained with the handles and a continuously variable pump system.The frame struts 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 enables the diagonal insertion of door spreaders. It is very simple to adjust the frame struts. Due to the telescopic rods, the tensioners can be adjusted to a length of 51 to 115 cm and are designed for a load capacity of 30 kg. If the pressure plates are angled, the load capacity is reduced to 25 kg.
