Self adhesive; just pull away the masking and stick it on! No more hunting around in the hardware store for exactly the right thickness of foam rubber weatherstripping. Exactly the same mute rubber found on USA Vintage Series reissue Jaguar. Great for restoring older Jaguars or for replacement use in USA Vintage Series instruments. Also great for Bass VI! Brand New. Genuine Fender 0054500049. UPC 717669612689. Photo may not reflect current Fender packaging.
