What's in the Box

This dropout battery box allows you to put your battery somewhere out of the way while still maintaining access. The box normally locks in the up position or it also drops down and locks 4-1/4" lower if needed. You can also drop the box completely out for maintenance.

Accepts batteries up to 10-1/2" long, 7" wide, and 8" tall.
