Key rings
The key stays on the bunch.
Sealed keyrings in solid stainless steel and flexible steel wire. Crimped with a tool — after that released only by cutting the ring.
Stainless steel keyrings
One piece of steel, one number.
A solid 4 mm ring in brushed stainless steel. Press closed, crimp, and after that released only by cutting the ring.
Developed for use in the Security Asset Manager and the Keycontroller — and just as good as a key ring on its own. Supplied in packs of 10 per size.
Five fixed sizes.
From one to four inches, measured as the internal diameter. How many keys fit depends on their thickness; the figures below are for standard building keys.

Sizes and order codes.
All five sizes from stock, in packs of 10 per size.
| Size | Internal diameter | Keys | Order code |
|---|---|---|---|

Ring thickness 4 mm solid stainless steel, brushed, with a stamped serial number. Supplied in packs of 10 per size.
Three tools.
Press closed, crimp, open. By hand, without power or settings. For the stainless steel keyring the closing and crimping tools are the minimum.



Perfectly smooth once crimped.
No protruding edge, no seam for a key to catch on. The ring can be used all the way round and opens only with the cutting tool.
Starter kit
Everything to get started, in one case.
Rings in the common sizes, the three tools and coloured ID sleeves. Including a sample of every size, so you can try out what fits.

Flex keyrings
Flexes with you, closes just as hard.
The same five sizes and the same serial number, but with a braided steel wire instead of a solid bow. For keys with a small opening.
The flex keyring is closed with the same crimping tool as the stainless steel keyring — the closing tool is not needed here.
| Cable | 2.6 mm braided stainless steel |
|---|---|
| Closure | 4 mm, smooth once crimped |
| Sizes | 1" to 4", the same as stainless steel |
| Tags | Aluminium 3 cm or acrylic 3 mm |
Two tools.
The flex keyring has its own crimping and cutting tools: one to squeeze the closure shut, one to cut it open again.


Flex keyrings
Five fixed sizes.
The same range of sizes as the stainless steel keyring, from 1 to 4 inches. The braided cable flexes, and once crimped the pressed closure is smooth and usable all the way round.
Number of keys per ring, indicative.
| Size | Internal diameter | Cable | Closure | Keys | Order code |
|---|---|---|---|---|---|
| 1" Flex | 3 cm | 2.6 mm | 4 mm | 14 | Flex KR3 |
| 1⅝" Flex | 4 cm | 2.6 mm | 4 mm | 22 | Flex KR4 |
| 2" Flex | 5 cm | 2.6 mm | 4 mm | 28 | Flex KR5 |

All sizes with their own serial number, from stock in packs of 10 per size.
Datasheet key rings.

Work instruction Tamper-Proof Key Rings.
Specifications, tools, and closing, sealing and opening the stainless steel and Flex keyring. Five pages with the manufacturer’s figures.
Morse keyrings
Closed by hand. Reusable.
A 4 mm stainless steel bow that clicks shut by hand into a plastic hub — without tools. Every hub has its own number.
For a new layout you replace only the hub; the bow stays in use. For situations where keys change regularly and a sealed ring goes too far.
Four models.
Three U-models for a handful up to a full bunch, and a round model of 8.5 cm. The same hub fits every model.
| Model | Size | Order code |
|---|---|---|
| U-model | 3.5 × 3.5 cm | KR3535 |
| U-model | 3.5 × 5.0 cm | KR3550 |
| U-model | 5.0 × 6.0 cm | KR5060 |
| Round model | 8.5 cm diameter | KR8500 |
Bow 4 mm stainless steel. Minimum order 10 rings per model.
A hub per department.
The plastic hubs are available in various colours and every one carries its own number. Colour for the department, number for the records.
Does the layout change? Then you replace the hub and keep the bow. Separate hubs can be ordered in packs of 25.
| Colour | Order code | Colour | Order code |
|---|---|---|---|
| Red | KH-01 | Brown | KH-06 |
| Yellow | KH-02 | Green | KH-04 |
| Blue | KH-03 | White | KH-08 |
| Black | KH-05 | Gray | KH-09 |
Separate hubs in packs of 25. The bow stays in use.
Rivet keyrings
Closed with a rivet.
Chromed steel of 2.5 mm. The ends are pressed together with pliers until the holes in the flat ends line up. A copper rivet goes through them, which you hammer tight on a solid surface.
| Diameter | Keys | Order code |
|---|---|---|
| 2.3 cm | 13 | RR23 |
| 3.5 cm | 19 | RR35 |
| 4.0 cm | 21 | RR40 |
Number of keys indicative, derived from the stainless steel range — in practice the thinner 2.5 mm ring takes slightly more.
Flexible with coating
Thin, flexible, closed with a twist.
Steel wire with a plastic coating, for situations where a thinner ring is needed. Closing and reopening is done without tools, with a twist. If the ring has to stay closed, squeeze the closure with a pair of pliers.
| Diameter | 4 cm |
|---|---|
| Keys | About 21, indicative |
| Closure thickness | 1.5 mm |
| Colours | Red, blue, grey, yellow, green and black |
Which ring suits you?
In short: how the ring closes, whether a tool is needed for that, and whether it can be reused.
| Version | Closure | Tools | Serial number | Reusable | Sizes | Order code |
|---|---|---|---|---|---|---|
| Stainless steel keyrings | Crimped, sealed | Closing and crimping tool | Yes, in the steel | No | Five, 1" to 4" | KR3 – KR9 |
| Flex keyrings | Crimped, sealed | Crimping tool | Yes, in the steel | No | Five, 1" to 4" | Flex KR3 – Flex KR9 |
| Morse keyrings | Clicks into a hub | None | Yes, in the hub | Yes, replace the hub | Four models | KR3535 – KR8500 |
| Rivet keyrings | Copper rivet | Pliers and hammer | No | No | Three, 2.3 to 4.0 cm | RR23 – RR40 |
| Flexible with coating | Twist, squeezed if required | None | No | Ja | One, 4 cm | On request |
Only the crimped stainless steel and flex keyrings are sealed: they make it visible whether the bunch has been tampered with.

Five ways to keep the key on the bunch, each with its own way of closing.
Frequently asked questions about key rings.
-
That differs per version, and that is exactly the point. The stainless steel keyring and the flex keyring are crimped and afterwards open only with the matching cutting tool — so an opened ring is always a visibly opened ring. With the Rivet keyring the rivet has to be broken. The Morse keyring clicks shut by hand and can be reused. The flexible coated ring has a screw closure that opens to change keys: handy with a changing layout, but not intended as a seal.
-
Three versions carry a serial number: the stainless steel keyring and the flex keyring have the number stamped into the steel and use the same numbering system; on the Morse keyring the number is on the hub, and every hub has its own number. So the number belongs to the ring itself and not to a label that can fall off — which keeps the bunch of keys traceable. The Rivet keyring, the flexible coated ring and the separate steel wire set do not have a serial number. The comparison sets out what you get per version.
-
There are five fixed sizes, from one to four inches. How many keys fit depends on the thickness of those keys, so no fixed number can be given. If in doubt: print the product sheet at actual size and lay your current ring on it. With a quotation we will look with you.
-
For the stainless steel keyring, three: pressing closed, crimping and opening. By hand, without power or settings. The flex keyring has its own crimping and cutting tools, two pieces. The Morse keyring closes by hand and needs no tools. There is also a starter kit with rings, tools and ID sleeves in one case.
-
Once crimped the ring is perfectly smooth: no protruding edge and no seam for a key to catch on. For situations where a thinner ring is needed, or where locks and surfaces have to be treated extra gently, there is the flexible ring with a plastic coating.
