Grip Head Tribology & Hollywood Rigging Protocols
Set Safety ProtocolsCDA 360 Solid Brass Friction Disc
150 FT-LBS LOCKINGSolid CDA 360 free-cutting brass friction discs eliminate galling and aluminum-on-aluminum seizure under extreme clamp tension, providing consistent, non-slip locking torque up to 150 ft-lbs (203 N·m).
Precision Broached V-Grooves
4-POINT TANGENT CONTACTBroached V-groove channels establish positive 4-point tangent contact around mounting pins and tubes. This prevents crushing hollow gobo tubes while completely preventing axial slip and rotation.
The Right-Hand Rule of Rigging
CLOCKWISE GRAVITY LOCKAlways orient the grip head so the downward load moment acts clockwise on the T-handle. Gravity actively tightens the knuckle brake discs; reversing the orientation causes premature loosening and fixture drop.
