Description
A slim adjustable strap hinge for timber gates, with a 400 x 40mm strap, a pointed end and an M16 threaded pin. The strap bolts along the face of the gate through four holes and turns up into a lug at the post end, slotted 25 x 16mm for the pin, which locks there with a nut and washer on each side. The pin's eye turns in a bracket on a narrow 130 x 35mm post plate, fixed to the post with four staggered holes. Every part has a gold coloured plated finish. In the box are the strap, post plate with pin, two nuts and two washers. The price shown is for one hinge, minimum order 2.

What you get
| Strap | One 400 x 40mm strap, pointed at the far end, with a turned-up slotted lug |
|---|---|
| Post plate and pin | One 130 x 35mm post plate with a bracket, carrying the M16 threaded eye pin |
| Nuts and washers | Two nuts and two washers to lock the pin in the lug |
| Not included | Screws or bolts for the strap and the post plate |
Why choose this hinge
Suits slim timber. The post plate is only 35mm wide, so it sits on a narrow post or a gate frame that has no room for the wider plates in this range. The 40mm strap fits on a ledge or top rail without overhanging it.
A longer reach than the 300mm straps. Four holes, spaced 110, 105 and 105mm apart, spread the fixings along 320mm of the gate. The first hole is square, to take the square neck of a coach bolt and stop it turning as you tighten the nut.
Adjustable after hanging. The nuts run along the 80mm shank to close or open the gap at the post. The 25mm slot on a 16mm pin leaves about 9mm of movement across the thickness of the gate.
A published weight limit. The supplier gives a maximum weight limit of 300kg for this hinge. It weighs about 1.23kg.

Is this the right hinge?
Each hinge below works in the same way. Against its neighbours, this one has the same pin and post plate as the 800mm M16 hinge but half the strap length, for gates where a long strap would be more than the frame needs. The M20 and M24 hinges have shorter, wider, black straps and a thicker pin. Choose by strap length and pin size.

Fitting
Use two hinges per gate, one near the top and one near the bottom. Fix the post plates to the face of the post so the brackets sit in line. Lay the strap along a ledge or rail where the fixings have solid timber behind them, and fit a coach bolt through the square hole by the lug. The sizes of the remaining holes are not published, so check your fixings against them before you start. Stand the gate on packers, pass each pin through its lug, fit the nuts and washers either side and set the gap. Tighten both nuts against the lug once the gate hangs true.
Care
Grease the pivot and check the nuts and fixings each spring. On treated timber, look at the fixings in the first few months, as new softwood often shrinks enough to loosen them.
Frequently asked questions
Is the price for one hinge or a pair?
One hinge, with a minimum order of 2 because most gates use a pair. A complete hinge includes the strap, post plate, pin, two nuts and two washers.
Is it black?
No. Every part of this hinge has a gold coloured plated finish, as pictured. If you want a black strap, the M20 and M24 hinges in the table above are black.
How heavy a gate will it carry?
The supplier publishes a maximum weight limit of 300kg for this hinge. That figure is for the hinge, not a rating for your gate, and the timber, the fixings and wind all limit what it can safely do.
Can I paint it?
Yes, you can paint over the finish if you want the hinge to match the gate. Key the surface first and use a primer suited to plated steel.
