Adjustable Wooden Gate Hinge M20, 900 x 300mm L Strap, Top Left Hand, 500kg

A long L strap hinge for wide timber gates, in the top left hand. The black steel strap has a 900mm arm that runs along the top rail and a 300mm arm that runs down the hanging stile, both 50mm wide. An M20 threaded pin on a separate post plate passes through a bracket at the corner of the strap, with a nut and washer on each side, so you can set the gate in or out after it is hung. You get the L strap, the post plate with its pin, two nuts and two washers. This is the top left-hand hinge, which also fits bottom right, so each gate leaf needs one of these and one top right-hand hinge. The price shown is for one hinge.

Why choose this hinge

A long reach along the rail. The 900mm arm has five fixing holes at 210mm spacing, so the load is shared along much more of the top rail than a short strap can manage. That matters on a wide gate, where the far end has the most leverage on the hinge.

The short arm braces the corner. The 300mm arm runs down the hanging stile with two more holes 200mm apart, tying the rail and the stile together at the corner where a timber gate starts to drop.

Adjust after hanging. Wind the two nuts along the M20 pin to move the gate in towards the post or out from it. The bracket at the corner of the strap has a 35 x 22mm oval hole, which gives the pin some sideways room as well when you are lining up the closing edge.

Rated for heavy gates. The manufacturer rates this hinge for gates up to 500kg. Posts and fixings must be strong enough for the gate you hang on them.

Which hand do I need?

Stand on the side of the gate where the straps will be fixed and look at the hanging post. This hinge, the top left hand, goes at the top of a gate hung on the left-hand post, with the plate on the post to the left and the long arm running away to the right. Turned over, the same hinge goes at the bottom of a gate hung on the right-hand post.

Order the matching M20 900 x 300mm top right-hand hinge with this one. Both hands are the same size and finish.

Where it is used

Wide timber field and farm gates, five-bar gates, close-boarded driveway and yard gates, and large timber doors on garages, barns and workshops, where a longer strap is wanted to spread the load along the rail.

Fitting and care

Fit the post plates first, one near the top and one near the bottom of the post, using coach bolts or coach screws to suit the 10.9mm holes. Stand the gate on packers in the closed position. Fit a nut and washer on each pin, pass the pin through the bracket at the corner of the strap, and add the second washer and nut. Then fix the long arm along the rail and the short arm down the stile. Set the gap at the post and tighten the nuts against the bracket from both sides.

To adjust later, slacken one nut, turn the other to move the gate in or out, then lock both again. Check the nuts each spring and put a drop of oil on the knuckles so the gate swings freely.
