These plates are designed to fill gaps around roll bar tubing that pass through sheet metal such as firewalls or rear parcel shelves
They can also be used to tie roll bar tubing into rockers, A and B Pillars
If switch panels, disconnect switches, fire system pulls or anything else is going to be mounted off the roll bar tubing these plates will simplify the process
The fill plates are 5" x 10" and are constructed out of 18 gauge steel (.050" thick)
