Linear Speed Limiters
 |  |
Put an end to lids and doors that slam shut or fly open—install these speed limiters for smooth, controlled motion.
Compression Speed Limiter—Compression speed limiters prevent closing doors from slamming.
Extension Speed Limiter—Extension speed limiters prevent doors from flying open.
Compression-and-Extension Speed Limiter—Compression and extension speed limiters prevent doors from slamming and flying open.
Adjustable—For speed limiters with adjustable resistance, pull the rod until it's fully extended, then twist it to change the resistance.
Free Travel of Stroke—Free travel of stroke is the percentage of the stroke that speed limiters move with no resistance, before speed control engages.
Maximum Cycles per Minute—A cycle is one rod stroke from extended to compressed and back to extended.

Precise-Control Linear Speed Limiters
 |
Regulate the speed or feed rate of drill presses, milling machines, lathes, and similar devices. These speed limiters have a knob with numbered scale so you can make precise adjustments to the resistance. Insert a rod in the mounting hole in the knob to rotate for adjustments.
A cycle is one rod stroke from extended to compressed and back to the original extended position.
0% Free Travel of Stroke—Free travel of stroke is 0%, so the entire stroke is speed controlled.
