This generator intrlock kit fits Siemens and Murray 100 Amp panels with a single, centered 100 amp horizontal-throw (left-right) main breaker and approx. 1 1/8" to 1 1/4" from main breaker panel edge to gen breaker panel edge.
 
The kit is VERY similar to the SMN-100 kit which is for panels with 3/4" to 7/8" spacing from main breakerpanel edge to gen breaker panel edge.
 
This is still a low production kit, so it will not be our signature blue anodizized color, but will be CNC machined to fit perfectly and look very professional.
