1 - Liftmaster LA400DC arm
Came quickly, installed in about 30 minutes, the wiring taking the longest but it works great.
Two liftmaster arms at perhaps half what our local installer would have charged. Delivered fast and in good shape. Installed in 30 minutes to save about $1,000. Great and thank you PSS

The LA400DC is the primary arm only. It can either be right or left. It is the one that is installed nearest the control panel.
