The M2 & M4 Aluminium Deck Mount Recessed Canister is a sleeve that can be fixed to wooden or concrete surfaces. Once the threaded ring is fixed to a surface the canister sleeve can thread up and down through the hole to give an ideal height. This canister can be used to recess a M2 & M4 fitting into a wall or deck.
