The speed clamps have an automatic engage and disengage locking mechanism. When released, the bracket can be rotated and fixed at each 10 degree angle. Both brackets have 2 female Euro-mounts for fitting an extension tube or Euro-adapter.
The brackets can be used on most dollies and the modular concept accepts not only GFM accessories but also accessories from other manufacturers. GF-HiLo Swivel Brackets can be used with the Combi-rig tubes or independently as off-set arms for mounting off-set bowls or Mitchell mounts.
