Genuine LiftMaster K74-39299-1 electrical box assembly for the SL595101U and SL595151U industrial slide gate operators.
Fitment: LiftMaster SL595101UL and SL595151UL only. The SL595103U/SL595203U use K74-39299-2 and the SL595105U/SL595205U use K74-39299-3 — the boxes differ by voltage and phase, so read the full model number off the data plate first.
Supplied as a complete e-box assembly. Order the boards separately if only the electronics have failed.
