LOB 72/55 Fire-Resistant Lock EI 30 Stainless Steel Rounded Faceplate 8mm

Product Overview

The LOB 72/55 (EI 30) Fire-Resistant Lock is designed for integration with certified door closers in fire-rated door assemblies. Intended for installers and OEM project managers, it is suitable for use in commercial and institutional facilities that require secure closure for fire protection. The lock is constructed with a rounded stainless-steel faceplate, features an 8 mm spindle, and is compliant with EI 30 fire resistance for 30-minute rated doors.

A defining feature of this SKU is its compatibility with both solid and glazed fire-resistant doors made of wood or wood-based materials, as tested in documented fire resistance tests. This versatility reduces procurement risk for contractors specifying multiple door types across one site. It is ideal for bulk procurement or OEM packages in commercial construction projects that demand standardized fire certification across various wooden and glass-enhanced door leaf designs.
