MODEL RB REEL BRAKE DESCRIPTION
The Model RB brake was originally designed as an economi-
cal modular brake for use on reels as an alternative to electric
brakes.
The unique modular design allows either a single or double
disc unit to be installed within the same mounting bolt circle
by simply changing the stud extensions and adding or
removing the appropriate components. Conversion kits are
available for this purpose.
The Model RB brake exhibits quiet operation, consistent
torque capacity, long life, and the ruggedness necessary for
emergency stops at an economical price.
