The lock lifts out while you weld and goes back in afterwards. A key turn throws a square deadbolt out by 24mm, and the supply includes a euro cylinder, three keys and a keep plate for the post. There is no latch and no handle: this lock is locked and unlocked with the key only. It can be fitted either side of a gate. The price shown is for one lock set.\u003c\/p\u003e\n\u003cfigure style=\"margin:16px 0\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0621\/3002\/8778\/files\/weld-in-dead-lock-40-x-40mm-box-section-drawing.jpg?width=1200\" alt=\"Drawing of the weld-in dead lock for 40 x 40mm box section showing the box, lock case and keep plate\" width=\"1200\" height=\"1200\" loading=\"lazy\" style=\"display:block;width:100%;max-width:760px;height:auto;margin:0 auto\"\u003e\u003c\/figure\u003e\n\u003ch2\u003eWhy this part works\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eIt is the frame, not an add-on.\u003c\/strong\u003e A surface lock bolts onto the outside of a finished gate.

A smaller frame needs a smaller lock box: the box is 40mm across, so it will not sit neatly in 30mm tube. If you want the gate to latch shut on its own without a key, you need a lock with a latch and handle as well, which is the sash version listed below rather than a dead lock.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYou want\u003c\/th\u003e\n\u003cth\u003eChoose\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDead lock for 40 x 40mm box section\u003c\/td\u003e\n\u003ctd\u003eThis lock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDead lock for 30 x 30mm box section\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/premium-weld-in-dead-lock-for-box-section\"\u003eWeld-in dead lock, 30 x 30mm\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDead lock for 25 x 25mm box section\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/weld-in-dead-lock-box-section-1\"\u003eWeld-in dead lock, 25 x 25mm\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLatch and deadbolt with handles, 40 x 40mm\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/premium-weld-in-sash-lock-double-throw\"\u003eWeld-in sash lock, 40 x 40mm\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFitting and care\u003c\/h2\u003e\n\u003cp\u003eTake the lock case out of the box before you start.

Let it cool, then clean and paint the welds before refitting the lock case, because welding spatter and hot-dip galvanising will both ruin the mechanism.
