Electrical interlock models and their dimensions have changed over the years, so the current model may require different wall dimensions than those used in the original installation.

This model can also be retrofitted to other chute systems using sheet metal adaptors and minor wall modifications for doors of the same nominal size — typically with minimal wall impact.
