Clean up those holes and add strength to your installation.
Firewall O-ring for making a firewall bulkhead. The rings have a 5-1/8" outside diameter with a 4' round hole. Each ring is predrilled and comes with 6 number 8 screws to mount it to the firewall.
NOTE: We can build the Custom bulk heads for you on a 6" or 12" long tube section with two O-ring clamps for $250.00 each. We suggest the customer build his own because each firewall is different . We can sell you everything you need in a raw kit form.
Can you please proof read for me? LOL j/k
We had told our website guy and he was suppose to fix both product descriptions for us. But I guess he didn't do it huh?
Thank you for bringing it to my attention.
