Avocet UPVC Door Butt Hinge 115mm Flat or Angled WMS

Avocet WMS uPVC Door Butt Hinge 115mm — Adjustable Hinge

Restore smooth operation to dropped or misaligned uPVC doors with this 115mm adjustable butt hinge — fit, adjust, and forget.

The Avocet WMS uPVC Door Butt Hinge is the precision replacement part you need when your uPVC door has started to drop, drag on the threshold, or no longer line up with the frame. Supplied as a single 115mm hinge in zinc alloy, this adjustable butt hinge offers up to 1.5mm of linear adjustment without removing the door from the frame — saving you the cost and hassle of a full door replacement. Compatible with uPVC door sashes featuring either a flat 0° or angled 13° edge profile, it is the trusted choice for repairs and like-for-like replacements on a huge range of UK uPVC doors.

Manufactured from BS1004A zinc alloy with 304 stainless steel hinge pins and a powder-coated finish of minimum 60-micron thickness, this hinge is built to outlast cheaper alternatives. Endurance tested to 20,000 cycles at 100kg per single hinge, it offers the durability and load-bearing performance expected of a professional-grade hinge.

Key Benefits for uPVC Door Owners:

• Tool-Free Adjustment Saves Time and Hassle – Up to 1.5mm of linear adjustment can be made without removing the door. Simply open the door to 90°, rotate the two adjuster cams until the marked points align, and you've corrected drop or drag in minutes — no lifting, no rehanging, no second pair of hands required.
• Avoids the Cost of a New Door – A dropped, dragging, or misaligned door is rarely the door's fault — it's almost always tired hinges. Replacing the hinges is a fraction of the cost of a new door or composite slab, and restores like-new operation.
• Built to Outlast Cheaper Alternatives – Zinc alloy body and leaf to BS1004A, 304 stainless steel pins, and a minimum 60-micron powder-coated finish mean this hinge resists corrosion, wear, and weather far better than budget pressed-steel replacements.
• Tested to 20,000 Cycles at 100kg – Endurance tested at a full 100kg load per single hinge, so it's rated for heavy uPVC and composite-style doors as well as standard panels.
• Reversible, Universal Fitting – Suitable for both inward and outward opening doors and either handing, so you don't need to worry about left-hand or right-hand variants when ordering.
• Choice of Edge Profile for Accurate Replacement – Available in flat 0° or angled 13° versions to match your existing door sash profile, ensuring the replacement seats correctly and the door closes square to the frame.
• Removable Pin with Security Grub-Screw – Makes initial assembly straightforward, while the security grub-screw prevents the pin being driven out from the outside — an important consideration for external doors.
• Helps Re-Seal Draughty Doors – A door that no longer sits square against its weatherseals is a door that loses heat. Fitting a fresh, adjustable hinge lets you re-compress the seals correctly and cut draughts that have been driving up your heating bills.
• White or Brown Powder-Coated Finish – Choose the finish that matches your existing door furniture for a clean, factory-fresh appearance.
• Buy Singly for Targeted Repairs – Need to replace just one damaged or worn hinge, or top up an existing set? Ordering a single hinge keeps the cost down and avoids paying for spares you don't need.

How to Identify Whether You Need a 0° Flat or 13° Angled Hinge:

The 0°/13° measurement refers to the angle of the flat plate on the hinge body — the part that screws onto the door frame. It must match the shape of the frame profile where your existing hinge sits. Choosing the wrong angle is the single most common cause of returns on butt hinges, so take a moment to check before ordering.

The simplest method — examine your existing hinge:

• If the hinge body's frame-facing surface is completely flat and sits square against a flat frame profile → you need the 0° (Flat) version.
• If the hinge body has a visibly angled or stepped face that sits against a chamfered (sloped) frame profile → you need the 13° (Angled) version.

If you can't tell from the hinge alone — check the frame profile:

• Open the door fully and look closely at the section of the door frame where each hinge is screwed on.
• Run your finger across the frame profile next to the hinge. A flat, square edge with no bevel indicates a 0° requirement.
• A visible chamfer or slope on the frame edge (typically around 13°) indicates a 13° requirement.

Please refer to the diagram in the product gallery for a visual reference. If you're still unsure, the safest option is to remove one hinge pin, slide off the hinge, and photograph it against the frame — then contact us with the image and we'll confirm the correct version for you.

Please measure your existing hinge carefully before ordering — particularly the screw fixing centres (73mm inner / 99mm outer) and the edge profile of your door sash (flat 0° or angled 13°). If you're unsure which version you need, contact us and we'll be happy to help identify the correct match.

Pro Tips:

Pro Tip: Fixing screws are not supplied because uPVC door reinforcement varies between manufacturers — some require self-tapping screws into steel reinforcement, while composite slabs require wood screws into the timber core. Always re-use your existing fixings where possible, or match the screw type to your specific door construction. If you're replacing one tired hinge in an older set, consider replacing all three at the same time — mismatched hinge wear is the leading cause of repeat door drop within 12 months of a single-hinge repair.

Frequently Asked Questions:

How do I know if I need the 0° flat or 13° angled version?
Look at the section of the door frame where your existing hinge body screws on. If the frame edge is completely flat and square, you need the 0° (Flat) hinge. If the frame edge has a visible chamfer or sloped face, you need the 13° (Angled) hinge. The hinge body itself will mirror the frame shape — a flat hinge body matches a flat frame, an angled hinge body matches a chamfered frame. See our identification guide above for a step-by-step check.

Will this hinge fit my uPVC door?
This is a 115mm butt hinge with screw fixing centres of 73mm (inner) and 99mm (outer), suitable for uPVC door sashes with either a flat 0° or angled 13° edge profile. Before ordering, measure the overall length of your existing hinge and check the screw centres match — if they do, and your sash profile matches, this will be a direct replacement.

Can I adjust the door without taking it off the frame?
Yes — that's the main advantage of this hinge over fixed-pin alternatives. Open the door to 90°, locate the two adjuster cams on the hinge, and rotate them until the marked points align with your desired adjustment. You get up to 1.5mm of linear movement, which is usually more than enough to correct typical drop or drag without removing the door.

Should I replace just one hinge or the whole set?
If a single hinge is visibly damaged, has a stripped fixing, or is significantly worn while the others are still in good condition, replacing just one is a perfectly valid repair. However, if the door has dropped or all three hinges are of similar age, we'd recommend replacing the full set — uPVC doors are heavy, and a single fresh hinge alongside two worn ones will quickly take all the load and wear out prematurely. Buying a single hinge makes sense for targeted repairs and spares; for whole-door rejuvenation, a pack of three is more economical.

Why aren't fixing screws included?
uPVC and composite doors use different fixings depending on the manufacturer — some require self-tapping screws into a steel reinforcement bar, while composite slabs need wood screws into the timber core. Because no single screw type works universally, we leave it to you to match the correct fixing to your specific door. In most cases, the original screws can simply be re-used.

How much weight can this hinge support?
This hinge has been endurance tested to 20,000 cycles at 100kg per single hinge — so a standard set of three is rated to support substantial uPVC and composite-style doors with comfortable headroom. The 304 stainless steel pin and BS1004A zinc alloy body are designed to maintain that performance for years of daily use without sagging.
