This item is currently out of stock.
Installing or replacing a roof vent usually means tracking down putty tape and the right screws separately - this kit bundles both so the job is ready to go out of the box.
It includes 8 feet of putty tape for sealing around the vent base and 24 #8 screws for mounting, enough for a standard installation with extra tape to spare for trimming and fit.
Handy to keep in the parts bin for the next vent swap or roof accessory mount.
