|This box was developed for builders who want a simple, light, all-stainless box that will fit in tight places, as it does not extend forward of the firewall as far as a standard box. Every part of the tri-box is stainless; including bushings, rivets, etc. It is furnished with a closed-cell silicone gasket. Weight is 9.6 ounces.|
Yes, the left hand model can be special ordered. Please contact our sales department for current pricing and availability on the left hand model and to place the special order.
The firewall mounting plate has dimensions of 5.125" x 3.25". The shaft extends 3/4" out of the box with an arm that measures 1.375". The apex of the box measures 2.75" perpendicular to the firewall.
