Whitco Euro Profile Double Cylinder – 10-Disc Each Side, Keyed Alike, Chrome Plate N843700
The Whitco Euro Profile Double Cylinder (code N843700) is a Euro-profile (C4) cylinder made to Whitco specifications for Whitco security door and window locks. It is a double cylinder that keys from both sides, with 10 discs in each half — the “2 × 10” in the code means 10 discs in each half of the one cylinder, not two cylinders. It is sold as each (a single cylinder unit), not as a pair. This listing is the 10-Disc Each Side, Keyed Alike configuration in Chrome Plate finish.

|---|---|---|
| Keyed Different (KD) | Each cylinder keyed to its own key. | e.g. W8412 (KD) |
| Keyed Alike (KA) | Cylinders keyed to the same key so one key operates them all — each is still sold individually. | W8422 / W8433 / W8436 / W8437 |

| 2 × 10 Disc | 10 discs in each half of the one double cylinder. | W843x |

The last two digits of a Whitco code are the finish (e.g. 17 = Black, 16 = White). Suffixes: KD = keyed different, KA / 5KA / 10KA = keyed alike, LC = less cylinder.
Available Finishes
Swatch colours are indicative only. Living/soft finishes develop a natural patina over time. Powder-coat colours may vary between batches.
10-Year Warranty
Is this cylinder sold as a pair or a single?
It is sold as each — a single cylinder unit. A Whitco double cylinder is one cylinder that keys from both sides; it is not two cylinders or a pair.
What does “2 × 10” mean?
It means 10 discs in each half of the one double cylinder, so it can be keyed and unlocked from both the inside and the outside. It is still a single cylinder, sold as each.
What's the difference between keyed different and keyed alike?
Keyed different (KD) means each cylinder has its own key. Keyed alike (KA, or N × KA) means a set of cylinders are all operated by the one key — for example 2, 3, 20 or 100 keyed alike. Project Keyed and Restricted Profile are dealer keying systems.
What locks does this cylinder suit?
It suits Whitco Leichhardt, Tasman and Tasman Escape security door locks and Whitco sliding patio door locks that take a C4 cylinder. C4 cylinders can be keyed alike to other C4 and CYL4 Whitco and Lockwood products.
How do I read the Whitco code?
The last two digits are the finish (e.g. 17 = Black, 16 = White, 08 = Bright Chrome, 11 = Silver, 19 = Primrose, 99 = non-standard). A trailing K means keyed alike; D5 or 5-disc refers to the cylinder; LC means less cylinder.
Is this finish in stock?
Silver and Black finishes are normally held in stock with the supplier. All other finishes are made to order — call Prime Hardware on 1800 329 028 to confirm availability and lead time.
What warranty applies?
Whitco products carry a 10-Year Warranty against defects in materials and workmanship, under the Australian Consumer Law. (Screen-door products and pneumatic closers carry 12 months.) Manufactured by ASSA ABLOY Australia.
