💡 What technical advantage do retractable leveling casters offer over fixed floor pads?
-Threaded M12 and half inch inserts allow quick height tuning to compensate for warped subfloors
-Internal spring mechanisms absorb tool vibration while locking the base plate flat against concrete
-Swivel release levers let mechanics shift the entire assembly between rolling service mode and rigid machining mode instantly
-Factory builders specify these foot assemblies because they distribute static weight evenly across multiple mounting points
