I have a new Chamberlain 1/2 hp chain opener, hope to install tomorrow.
Instructions say I gotta install elec. safety lites inside door. Questions:
1.) What (if any) code requires safety lites? 2.) Practical to install and use opener without 'em?Replacing failed opener. Did fine w/o safety lites on old openers for 20+ years. Tired of playing ladder-monkey, stapling wires in gar. rafters.
Thx, Willie
