Euro Cylinder Sash Lock - Product Features & Advantages
- EN1634 260-Minute Fire Resistance for Life Safety: Engineered to maintain functionality during extreme heat (840°C for over 4 hours)—critical for compartmentalizing fires in offices, hotels, and multi-story residential buildings. Prevents fire spread through entrance doors, providing extra evacuation time for occupants.
- BS EN12209 Grade 3 Anti-Intrusion Security: Undergoes rigorous testing for anti-pick (10-minute resistance), anti-drill (5-minute resistance), and anti-snap (800N force resistance). The 2-turn deadbolt (18mm projection) ensures deep frame engagement, deterring break-ins at retail storefronts or residential front doors.
- Full SUS304 Construction for All-Environment Durability: All critical components are made of SUS304 stainless steel—resisting corrosion from coastal humidity, cleaning chemicals, or bathroom moisture. Passes 240-hour salt spray tests, outperforming zinc-alloy locks that degrade in harsh conditions.
- Euro Cylinder Versatility for Custom Security Levels: Accepts a range of Euro profile cylinders (sold separately): - Single cylinder: Key operation external, thumbturn internal (ideal for residential front doors) - Double cylinder: Key operation both sides (high-security office storage rooms) - Smart Lock cylinder: Bluetooth/NFC keyless access (modern hotels or co-working spaces) All cylinders operate both latch and deadbolt for streamlined use.
- Seamless Integration with D&D Door Hardware Ecosystem: The 8×8mm follower fits D&D’s stainless steel door handles (matching PVD/SSS finishes) and door closers (ensures automatic latching after use). Compatible with panic exit devices for commercial emergency egress—reducing cross-product compatibility issues.
Euro Cylinder Sash Lock - Installation & Operation Steps
- Pre-Installation Preparation: - Confirm door thickness (40–90mm) and select matching backset (45mm for slim doors, 60mm for thick office doors). - Choose forend design (Square/Radius) and finish (coordinate with D&D’s Stainless Steel Door Stops or door handles). - Select compatible Euro cylinder (single/double/smart lock variant) based on security needs. - Gather tools: 3mm/8mm drill bits, chisel, Phillips screwdriver, tape measure, pencil, level (critical for fire safety—misalignment causes heat leakage).
- Mark & Create Mortise for Fire Safety: - Use the included template to mark the mortise outline on the door edge (align backset line with door center). - Drill pilot holes along the outline to prevent splitting, then chisel the mortise to fit the lock body (depth = 85mm; width = forend width). - Chisel a 3mm-deep recess for the forend—ensures flush installation (prevents heat buildup gaps during fires).
- Install Lock Body & Test Mechanisms: - Insert the lock body into the mortise, align the forend with the recess, and secure with SUS304 screws (tighten to 6–8 ft-lbs torque—over-tightening warps the lock, compromising fire resistance). - Insert the Euro cylinder and test operation: - Latch bolt: Press lever handles on both sides to extend/retract (confirm smooth movement). - Deadbolt: Turn cylinder 2 full rotations to extend (18mm projection); reverse to retract—ensure no sticking.
- Mount Strike Plate & Integrate Fire-Safe Hardware: - Close the door, extend the deadbolt, and mark the strike plate position on the frame (use a level to avoid misalignment—gaps reduce fire resistance). - Chisel a recess for the strike plate (depth = plate thickness) and a 19mm-diameter hole for the deadbolt to engage. - Secure the strike plate with long screws (penetrate frame studs for strength); attach D&D’s door closer (adjust closing speed to 3–5 seconds for automatic latching).
- Final Fire Safety & Security Testing: - Operation Test: Lock/unlock 20 times with the cylinder; check that both latch and deadbolt function smoothly. - Fire Seal Check: Ensure no gaps between forend and door edge (use fire-rated sealant if needed, per local codes). - Maintenance: Lubricate moving parts with high-temperature graphite grease (resists 260°C+) every 6 months; clean forend with a damp cloth weekly.
