The LiftMaster K13-10024 Limit Nut, Commercial is a genuine replacement component used in the rotary limit system on LiftMaster commercial door operators. It threads onto the limit shaft and is adjusted to establish the exact open and close stopping points of the door, helping prevent over-travel and ensuring consistent, repeatable operation. This part is commonly found in LiftMaster commercial overhead door openers that use a threaded limit shaft assembly, including many J-, H-, T-, GT-, and GH-series units. Always confirm compatibility by checking your operator’s parts diagram or service manual for part number K13-10024.
Use this limit nut when repairing or fine-tuning the limit assembly on sectional or rolling steel door applications in commercial or industrial settings. Installation and adjustment should be performed with power disconnected and according to the operator manual: position the door, thread and set the nut to the desired stop, and verify both travel limits with a full open/close test. Properly setting the limit nut protects the operator and door system by ensuring the microswitches actuate at the correct points. This OEM LiftMaster part is ideal for maintenance, replacement, or upgrade of worn or stripped limit hardware on compatible commercial garage door operators.
