Genuine LiftMaster K74-39299-2 electrical box assembly for the SL595103U and SL595203U industrial slide gate operators.
Fitment: LiftMaster SL595103UL and SL595203UL only. The SL595101U/SL595151U use K74-39299-1 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.
