The Locinox H-METAL insert lock has a high quality 100% stainless steel mechanism. The massive stainless steel hook and adjustable latch bolt makes this a one of a kind lock. The center distance between the cylinder and the handle is 92 mm. The combination of the hook (dead bolt) with the corresponding keep (order separately) provides a secure anchoring of your gate. These locks can be used on metal or aluminium gates.
