Zinc
Zinc Alloy is the most fundamental material for the Wixroyd product range. Housings, inserts, handles, spacers, keys, hinges etc, are all die cast products. The zinc used is a zinc alloy with the following contents (except zinc): Al 4,03% Cu 0,83% as well as minor contents of Mg, Fe, Pb, Cd, Sn and Ni.
Plastic - Polyamide
Many of our products are made of injection moulded plastic, normally polyamide. When needed, we add fibreglass to the material in order to optimise qualities of the product. Examples of products made out of polyamide: handles, housings, rod guides etc.

FAQs
When selecting a Wixroyd Cam Latch for your application, you need to answer these questions:
1. Which installation cut out?
2. Which body style?
3. Which locking key?
4. Which accessories?
5. Which cam type and size?
Step 1: Which installation cut out?
Cut Out
All our Flexi-System Cam Latches use a standard installation cut out 22,2 dia, 20,2 square, for maximum flexibility. We also provide a number of alternative cut out dimensions for legacy/historical installations.
Step 3: Which locking key?
Standrad insert driver keys
Our range of Insert Driver Cam Latches require a simple key to actuate. Refer to part A0102 and A0103 for correct keys.
Cylinder Locking
Our Cam Locks with Cylinder Locks are supplied with two keys per lock. Available as Euro key 5333, keyed alike or keyed to differ locks.
Step 2: Which body style?
Material and finish
Select from our variety of die-cast zinc, polyamide plastic and stainless versions.
Actuation and locking method
Standard insert driver type, cylinder lock or wing handle type.
Number of latching points in application
Typically, Single Point Latching is required, but the Wixroyd Flexi-System also provides Multi-point Latching (typically 3 point - at lock point, top and bottom of cabinet).
Step 4: Which accessories?
- Multi Point latching: use our rod set A0303 or A0325 for suitable rods and rod guides.
- Finger Pulls: easily installed with any of our flexi-system cam bodies, finger pull no. A0352 is a simple, cost effective handle for your cabinets.
- Dust cap: to reduce material ingress.
Step 5: Which cam type and size?
Wixroyd Cams are available in a number of different materials; zinc plated steel, stainless steel (AISI 304) and black plastic.
With or without "Projection"
Different cam bodies require cams either with or without projection.
With Projection Cams prevent turning of the cam over 45°, but is not suited to all cam bodies. For correct projection type, please see individual cam body technical pages.
Number of Latching Points
Single-point Cams are suitable where just single point latching is required. Multi-point cams are for applications requiring 2 or 3 latching points.
Calculation of correct cam off-set
This is the most important aspect of the selection process. As well as being with or without "projection", cams vary in two key aspects.
Cam off-set (dimension ch)
To ensure your cam fully and correctly engages with the frame of your door, the correct cam off-set must be selected. A cam off-set can be either negative (-ve) or positive (+ve).
Cam length (dimension cl)
This impacts the reach of the cam to door frame and hence impacts positioning of cam body for installation. Cam length is measured from the centre of the cam fixing hole to the cam's leading edge. Most typically cams are 45 mm in length.
Use formula to calculate ch (required cam off-set), and refer to the cam selection chart.
ch = h - lh where;
ch = the required cam off-set/height
h = grip length (distance between inside of latch face and front of cam)
lh = body length of cam latch/lock to be used (see example below)
Example of calculation of correct cam off-set
Example One
Cam body A1003.AW0010 has been selected for the application. If we refer to the data sheet for this part, suitable cams are parts A0203, A0210 or A0240 - "without projection".
Know application information: h=26 lh = 18
Therefore: ch = 26 - 18 =+8
Cam off-set of +8 is required.
Using the data tables for cams A0203, A0210 and A0240 we can select the following cams without projection with an off-set of +8; A0203. AW5408 (steel), A0210.AW0428 (stainless) or A0240.AW0108 (three point cam).
Example Two
Cam body A1003.AW0010 has been selected for the application. If we refer to the data sheet for this part, suitable cams are parts A0203, A0210 or A0240 - "without projection".
Know application information: h = 14 lh = 18
Therefore: ch = 14 - 18 = -4
The required cam off-set is negative, -4 as the application's door frame is effectively shorter/lower than the length of the cam body.
Using the data tables for cams A0203, A0210 and A0240 we can select the following cam without projection with an off-set of -4; A0203.AW6404 (steel).
Installation
Our flexi-system is based on a standard installation cut out 22,2 Ø and 20,2 sq.
Option 1: Installation when fully assembled
When cam latch grip (h) is 9mm or more this method is possible
- With the cam body and cam fully assembled, attach the sealing washer to cam body.
- Tilt the latch 45° and pass it, cam fi rst, through the installation cut out in the panel.
- When in place attach the fi xing nut to the cam body to secure. Tighten to 10 Nm max.
Option 2: Installation unassembled
When cam latch grip (h) is less than 9mm this method is suitable
- Prior to commencing ensure that the cam body, cam, cam screw, fi xing nut and sealing washer are completely unassembled.
- Attach sealing washer to the cam body and pass through installation cut out in panel.
- Attach the fi xing nut to the cam body to secure. Tighten to 10 Nm max.
- Attach the cam to the cam body. Once you have ensured the cam has the correct orientation toward the panel frame, secure with cam screw and tighten to 4 Nm.
Technical Specs
IP Ratings
A product classifi ed to an IP rating has either been tested in an independent laboratory, or due to the resemblance of its structure to a tested product, classified as IP.
Important note: We can only guarantee our products correspond to the indicated classification when assembled and used correctly.
IP 65: Dust Tight and Jetting Secure. Through the application of an o-ring and a flat gasket, this higher classifi cation can be achieved.
IP 54: Dust and Splash Protected. This is the standard classifi cation for our products. Equivalent to NEMA3.
| Character | Value | Standard |
| Density | 1,35 g/cm3 | DIN 53479 |
| Hardness | 65 Shore A | DIN 53505 |
| Breaking Strain | 5 N/mm2 | DIN 53504 |
| Expansion | 200% | DIN 53504 |
| Heat & cold resistance | max. 70°C, min. -35°C |
Through the application of a flat gasket between the lock and the door, class IP 65 or NEMA 4 is achieved
Pressure deformation test
| Time/temp. | Type of test | Standard | Result |
| 22h/100°C | DVR | DIN 53517 A | 9% |
| 70h/100°C | DVR | DIN 53517 A | 12% |
The flat gasket is made out of a mixture of NBR (Nitrile Rubber) and SBR (Styrolbutadiene Rubber). This gives the gasket a satisfactory chemical resistance and a good constancy to oil.

Knowledgebase Questions
No.
The bodies of the a1003 cam latch will not accommodate the insert from the A25xx series. The body designed for the WT or L handle is larger. You can however swap the T for an L andle.
Yes – the B4590
No – Stainless steel is harder than zinc or regular steel, so requires different tooling.
Yes, if it already exists, like the A1103 for the A1003. If a part has no existing stainless steel corresponding part, it cannot be produced in small quantities. Although the dimensions may be the same, stainless steel requires different tooling and production techniques to zinc or steel, so the start up costs for machining are prohibitively high.
Euro Key is a cross factory key. It means that no matter the manufacturer, a Euro Key will actuate a Euro lock. “Keyed Alike” means that it is a factory standard key. All locks bought from a manufacturer will be opened by a standard key. But the keyed alike key will not open a Euro lock, nor will it open a “Keyed Alike” lock from another manufacturer.
A master key system is one in which the locks bought keyed to differ can all be opened by a single key. The ley for one lock cannot open another lock, but a master key can open all locks to which it is assigned.
Both the cam locks have the same action; the key can be removed in the unlocked position but the key is retained in the locked position.
Wixroyd cam locks are supplied in keyed alike, where all the locks will have the same key, or keyed to differ, where each lock has a unique key. We can produce a system in which a number of locks share a key, but this is a non standard requirement and not standard. Because of the cost on the machine being programmed to produce a fixed number of key combinations, it is not economical for quantities of locks under the hundreds.
