When You Can't Source the Hinge You Need
Standard hinges are everywhere. The trouble starts when yours isn't standard: a discontinued boat hatch hinge, an offset stainless piano hinge nobody stocks in your length, a heavy-duty bearing hinge in an odd leaf size, or a hinge that has to land on an existing hole pattern you can't move. You search every catalogue, post on the forums, and still come up empty — because the hinge exists on your door, just not on any shelf.
That's the hinge EKINSUN makes. Send the worn or broken original — or photos and the hole spacing — and we machine a replacement to match it exactly, in the right material for where the door lives. No drawing, no part number, single pieces welcome.
Hinge Types We Make
Reproduced from your sample, or made to your sizes — most without a drawing:
| Hinge type | Typical use |
|---|---|
| Butt | Doors, cabinets and lids — the standard leaf-and-knuckle hinge |
| Strap & T-strap | Heavier doors, gates, hatches and lockers needing broad support |
| Piano / continuous | Long lids and panels — made to your length, leaf width and knuckle count |
| Offset | Set-back or overlay doors where the pivot must sit off the leaf line |
| Flush-mount | Where leaves must sit level without mortising |
| Bearing / heavy-duty | High-cycle or heavy doors — bearing knuckles to resist sag |
| Marine hatch / deck / seat | Boats and decks — 316 stainless against saltwater corrosion |
| Weld-on & concealed | Fabricated structures and clean-look interior doors |
When Off-the-Shelf Won't Do
These are the situations a catalogue can't solve — and where a made-to-order hinge is the only real fix:
- Discontinued boat or RV hinge — the maker dropped the model or closed. See obsolete & discontinued parts.
- Offset or odd-length piano hinge — the classic "where do I even source this?" problem.
- Must match an existing hole pattern — re-drilling the door or frame isn't an option.
- Heavy-duty in 316 — you need marine grade and strength, not a light zinc casting.
- Worn pin or knuckle — the leaves are fine but the hinge sags or has play.
Materials — Matched to the Environment
Marine & outdoor
316 stainless for saltwater and deck exposure; aluminium bronze where you want corrosion resistance with a traditional look.
316 stainless →Interior & industrial
304 stainless, brass and aluminium for cabinet, panel and interior doors — strong, with plating or anodising options.
304 stainless →Pins & bushings
Hardened stainless or bronze hinge pins and knuckle bushings — often the real fix for a sagging hinge.
Bushings →Made From Your Old Hinge
Send the hinge or photos
Mail the worn or broken hinge, or send photos with the leaf sizes and hole spacing. We confirm what's usable first.
Measure & rebuild
We capture the leaf dimensions, knuckle count, pin diameter and exact hole pattern, and rebuild the CAD to the original size. How reverse engineering works →
Confirm, machine & ship
You approve the drawing (free), then we machine, finish and inspect it against your sample. Reproducing from a sample →
What to Send Us
To quote a matching hinge fast, send what you can measure:
- The worn or broken hinge, or photos open and closed from several angles
- Hole pattern — screw/bolt hole spacing, diameter and countersink (the part that must match)
- Leaf length and width, and overall open length
- Knuckle / barrel count and pin diameter
- Handing or offset, if any, and whether the pin is fixed or removable
- Material/finish you need — or ask us to advise for the environment
- Quantity (one, a pair, or a matched set) and delivery country
No CAD, no part number, no problem. Rebuilding the geometry is our job — free, and confirmed with you before anything is cut. See how to order with no CAD file.
A note on branded hinges. We make a compatible replacement to the original's form, fit and function from what you supply. We don't sell branded original products or imply affiliation with any hardware brand.
Frequently Asked Questions
Yes — discontinued and unobtainable hinges are the main reason people come to us. Send the worn or broken hinge, or photos with a couple of measurements, and we machine a matching replacement. No catalogue number, drawing or CAD file needed.
Yes, and it's the most important part of a hinge replacement. We work to your existing screw or bolt holes — spacing, diameter and countersink — so the new hinge drops onto the same fixings without re-drilling the door or frame.
Butt, strap and T-strap, piano/continuous, offset, flush-mount, bearing/heavy-duty, concealed, weld-on and marine hatch, deck and seat hinges — in 316 stainless for saltwater, 304 stainless, brass and aluminium for interior and industrial use, with bronze or stainless pins and bushings.
Yes. For saltwater and deck exposure we machine in 316 stainless. Continuous (piano) hinges are made to your length, leaf width, knuckle count and pin size — including offset and odd lengths that are hard to source off the shelf.
Yes. A worn pin or knuckle bushing causing sag or play can be remade in hardened stainless or bronze without replacing the whole hinge, when the leaves themselves are sound.
Yes — one piece, no setup fee on machined parts. A single replacement hinge to get a door or hatch working is welcome, and we also make matched sets for a refit or fleet.
Send the hinge or photos and you get a quote within 24 hours. After approval a single machined hinge is usually days, not weeks. CAD reconstruction is free with your quote.
