The 4181 with a euro-cylinder (PZ) entry — for sliding doors that need a keyed lock without breaking the flush face. PZ is the European-cylinder cutout. Specified when a sliding door needs a real keyed lock — main-entry sliding gates, secured studio rooms, or hospitality applications where the privacy lock has to be more than a turn-button.
Every Tupai handle is available across the full PVD and satin palette. Finish photographs come from Tupai's product photography; ask us for finish-specific samples.
Tupai's house zamak alloy with PVD or satin finishing — the same material vocabulary as the Tupai swing-handle range. Stainless options available on selected references.
