What variations does the MK8 Window Winder come in, and what are the codes?
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. Range: • Mild Steel Chain (W3802xx) — Standard chain — suits most inland applications. • Stainless Steel Chain (W3803xx) — Corrosion-resistant chain for coastal or high-humidity locations. • Push-to-Lock (all shown models) — Key-locks the window closed (child safety / security). • Keyed Alike (K) (codes ending K) — One key operates a set of 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.
Does this W380299 winder lock?
This is a Push-to-Lock configuration — it key-locks the window closed for child safety and security, using a 5-disc cylinder.
