Yacob Fixed Knob Lever Handle Set U-Form Left Stainless Steel PN-EN 1634-1 Fire Rated

Product Overview

The Yacob fixed knob-lever door handle set with oval escutcheon is constructed from satin-finished 304 stainless steel for installation on left-handed fire-rated doors. Designed for commercial and institutional interiors requiring a high standard of safety, it provides compatibility with euro-profile cylinder locks and includes a freestanding round fixed knob and U-form lever. The hardware is certified for fire resistance in accordance with PN-EN 1634-1:2014-3 and features corrosion resistance class 3 for use in demanding environments.

A defining feature of this model is its formal fire resistance attestation (PN-EN 1634-1:2014-3) verified on a complete doorset, which directly supports fire safety compliance in procurement for new builds or upgrades. This certification mitigates risk of non-conformity in projects subject to formal fire-protection audits. The product is particularly well-suited for bulk specification in commercial, healthcare, and institutional doors up to basic durability rating (category 1).
