Description & Fitment
The ATB A-GB51 is an aluminum generator box with a smooth body and a diamond tread plate top lid that opens on gas springs. Stainless steel louvered grills on the left, right and back sides let air through, and a smooth front access door gives a second way in. The lid closes on a pull handle lock. ATB sells the M3200D mounting kit separately.

Order the M3200D mounting kit separately; ATB covers installation in its Installation Catalog.

Frequently Asked Questions
Will my generator fit?
Compare your generator's measurements, with handles, against the box size in the table and leave space around it. Contact us with the model and its dimensions if you want a second check.
How do I choose a generator box size?
Measure your generator's height, depth and width (including handles and wheels) and add room for airflow and cords, then pick a box whose inside fits it. ATB asks buyers to check the dimensions carefully against their needs before ordering.

Stainless steel louvered grills on the left, right and back sides let air through the box.
