MK8 Chainwinder Variations & Codes

Configuration What it does Whitco code

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.

What's the difference? The differences are the chain material and the locking. A mild steel chain suits most inland jobs; a stainless steel chain resists corrosion in coastal or high-humidity locations. Push-to-lock models key-lock the window closed for child safety and security, and the keyed-alike (K) option lets one key operate several winders.

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.
