MB1 Mule Block

MB-1 is a single-wheeled ball-bearing pulley; MB-2 is a double wheeled ball-bearing pulley and is used for muling double lines. Mule Blocks are a means of allowing lines to pass over the edge of a sill without rubbing or binding. Can also used to re-route track operating cables through a wall or ceiling.

Dimensions: 2” long x 1-3/8” wide x 1-7/8” high. 

Weight: 1 - 4 oz. 

IMPORTANT NOTE: Adding turns of any degree to operating lines increases the overall load of the system. Allowance must be made for this additional loading when machines are used to operate the systems. The use of pulleys with wheels larger than those used in the MB series will lessen the effect of the added load.
