LiftMaster K10-3515 Retainer Guide for SL580 and SL590 Slide Gate Operators
The LiftMaster K10-3515 retainer guide is a replacement guide component used on select SL580 and SL590 commercial slide gate operators. Retainer and guide parts help keep the related mechanical assembly positioned correctly as the operator cycles. When this type of part is worn, cracked, missing, or incorrectly installed, the associated mechanism may shift, bind, rattle, or wear unevenly. Because the retainer guide works with surrounding hardware, it is important to inspect the neighboring brackets, fasteners, and contact surfaces before replacing only the guide. This is a mechanical guide component, not a limit switch, chain, idler, circuit board, or sensor. Fitment should be confirmed from the SL580 or SL590 parts diagram because slide gate operator parts with similar names can differ by size, mounting hole location, and operator series.

Professional Advisory
Gate operators can contain moving mechanical parts, stored force, battery circuits, and high-voltage wiring depending on the model. Do not bypass safety devices or operate the gate with exposed, loose, or damaged components. If the operator has unsafe movement, burned wiring, power problems, or missing safety protection, have the system inspected by a qualified gate technician.
