Overview

The Ningbo Dimon Narrow Stile Mortise Lock is a commercial-grade architectural security lock engineered specifically for narrow-stile aluminum framed glass doors, patio sliding doors, commercial storefront entries, and metal passage gates. Built with a heavy-gauge zinc-plated steel case, laminated stainless steel faceplate, and precision brass cylinder, it provides maximum resistance against prying, forced spread, and jimmying. Available in two specialized locking configurations: a laminated Flat Deadbolt (for swinging aluminum doors) and a heavy-duty Hook Bolt (for bypass and pocket sliding glass doors), both operated by a smooth double-sided keyed cylinder.

Key Features

• Dual Locking Bolt Configurations:
  • Hook Bolt Tongue: Heavy-duty pivoting laminated hook bolt anchors into the strike cavity, locking sliding door leaves together to prevent them from being pried off their tracks.
  • Flat Deadbolt Tongue: Multi-ply laminated rectangular steel deadbolt provides high shear strength and anti-saw protection for commercial swing doors.
• Compact Narrow-Stile Profile: Slim mortise body fits seamlessly inside shallow aluminum extrusion channels (stile depth from 30 mm to 45 mm) without weakening structural frames.
• Double-Sided Keyed Security: Precision solid brass pin-tumbler cylinder operates smoothly from both interior and exterior sides, supplied with computer-milled keys.
• Corrosion-Resistant Galvanized Steel Case: Thickened, reinforced metal housing resists moisture, oxidation, rust, and salt spray in both interior and exterior installations.
• Smooth 360° Key Turn Action: Precision-machined internal cam linkages and gears ensure low operating torque and long mechanical cycling life.
• Complete Security Hardware Set: Comes fully assembled with mortise lock body, double-sided cylinder, stainless steel faceplate, strike plate, and mounting fasteners.
