Heavily constructed but well thought out with the foam allowing protection for the underside of the battery from the fasteners used to secure the tray. The webbing straps provided are also of good quality.

Have now used two of these in my total canopy power system. Photos below show the mounting location but prior to having installed the battery trays underneath the batteries.

great battery holders easy to install straps where unfortunately to bulky for us to use for this project.

Good quality, well made battery box. Does add to the height of the battery particularly when installing, so in tight locations, you will need to take account of this. For example: if the bare battery fits under a ledge, once you have fixed the tray in that location, you may no longer be able to put the battery into the tray!
