They gives a better grip for 80mm T-handles, even in cold weather.

Just as the name suggests, the Grip Helper is like three Grip Heads in one. Two independent grip heads sandwich a third with a fixed 16mm pin. This system allows multiple light control accessories to mount in front of fixtures without the need for numerous light stands.

The 5/8″ Gag Closed allows one 5/8″ (16mm) rod to be joined and positioned anywhere in 360 degrees with either a 5/8″ (16mm) rod or a 3/8″ (10mm) rod. The 5/8″ Gag Closed works perfectly for adding reinforcement components to a rigging structure. The option to convert from 5/8″ (16mm) rod to 3/8″ (10mm) rod gives you added flexibility for your rigging needs.
