Button operated safety detents for use with all 3" travel clamp type push pull cables. We have redesigned the "B" Series Control from the knob down. Three rugged zinc alloy castings have replaced 6 stampings, 12 welds, 4 rivets, 4 clinch nuts and a 5 piece indicator strip. Optional single lamp panel lighting has been replaced by standard twin lamp illumination. Dependable nylon bushings suspend the one piece lever and gimbal assembly between the main body castings. The removal of 3 phillips head screws allows complete disassembly of this unit.
