copy of Olympic jaw clamps HMS LOCK JAW ZG1500...in a warehouse
Sveltus 1648 blue Olympic clamps are made of very durable plastic.
The design and principle of opening and closing the clamps make them very easy to use. Additionally, they are very "fast" so closing and opening the clamps is not time-consuming.
The switch, which is built into each clamp, acts as a fuse and effectively prevents the clamps from opening during the exercises.
