The D&D Technologies MagnaLatch 3 Series, specifically the Top Pull model, is a gate latch designed for various applications, including swimming pool safety barriers. Installation requires adherence to local fence and barrier codes, with specific attention to height requirements for the latch release knob and overall fence height. Proper installation and maintenance are crucial for reliable operation, and the system is not a substitute for adult supervision, particularly around swimming pools. This article details the installation procedure, maintenance guidelines, and safety considerations based on available documentation.
Installation Procedure
The installation of the MagnaLatch 3 Series Top Pull model involves several steps to ensure correct alignment and functionality. Before beginning, it is advisable to consult local authorities regarding specific safety requirements and regulations pertaining to pool fences and barriers. The documentation emphasizes the importance of verifying these requirements before installation.
- Gap Measurement: The gap between the gate frame and the latch post should be between 3/8” (10mm) and 1 7/16” (37mm), with 3/4” (19mm) being ideal.
- Mounting Bracket A Installation: Determine the location for Mounting Bracket ‘A’ by measuring upwards from the bottom of the gate. For a latch release knob height of 54”, the measurement should be 36 3/8” (925mm). Secure the bracket to the post using one 1” (25mm) wafer-head, self-drilling screw through the side fixing hole, followed by two additional screws through the front of the bracket.
- Mounting Bracket B Installation: Measure upwards from Bracket ‘A’ 13 3/8” (340mm) to locate the position for Mounting Bracket ‘B’.
- Latch Body Installation: Slide the Latch Body ‘C’ down onto Mounting Bracket ‘B’, ensuring the rear track of the latch slides over both brackets ‘B’ and ‘A’. Secure the Latch Body to Bracket ‘A’ using a single 10mm (3/8”) countersunk screw ‘H’. The documentation specifically advises against using a power or cordless drill for this step.
- Striker Body Installation: The Striker Body ‘D’ slides onto a dovetail track within the Mounting Plate. It is adjusted using an internal adjustment screw; a powered drill should not be used for this adjustment. Position the Striker Body to maintain a 3mm (1/8”) gap between the lower part of the latch and the top of the Striker Body. Secure the Striker Body with two 25mm (1”) screws. Two small cylindrical dress plugs are provided to cover the screw holes.
- Final Adjustments: Open the gate and secure two more screws through the side leg of the Mounting Plate. If the gate frame width is 38mm (1 1/2”) or greater, an additional step is required. With the gate open, adjust the Striker Body using a screwdriver in the adjustment screw, turning counter-clockwise until the two holes are exposed. Fix the two remaining screws to secure the Mounting Plate.
- Alignment Check: Adjust the Striker Body to align with the Latch Body. Open and close the gate to verify the latch operates correctly, making adjustments as necessary to ensure safe operation. Vertical adjustment of the latch can be achieved by removing screw ‘H’, sliding the Latch Body up or down the post, and reinserting the screw into the appropriate hole.
Height Requirements and Safety Standards
Specific height requirements are outlined for child safety gates, particularly those used for swimming pools. These requirements vary depending on local regulations but generally include:
- Latch Release Knob Height: A minimum height of 54” (1370mm) or 1500mm (59”) depending on the documentation consulted. The documentation provides conflicting details regarding this measurement.
- Fence Height: A fence height between 48” & 72” (1220 & 1830mm) or 1220mm & 1520mm (48” & 60”) depending on the documentation consulted. Again, the documentation provides conflicting details.
It is crucial to confirm these and other requirements with the appropriate pool or safety authorities in the area and to install the latch in accordance with local fence/barrier codes and regulations. Pool gates should open outward, away from the pool, and the latch should be fitted to the outside of the gate. The documentation stresses that swimming pool fences, gates, and latches cannot substitute for adult supervision.
Maintenance Guidelines
Proper maintenance is essential for ensuring the continued reliable operation of the MagnaLatch 3 Series Top Pull model. The following guidelines are recommended:
- Key Removal: Always remove the key from the lock after use.
- Lubrication: Do not lubricate the latch with petroleum-based lubricants. Use only powdered graphite.
- Screw Tightness: Ensure all screws or bolts are tightened firmly.
- Debris Removal: Keep the release knob [F] and latching bolt free of sand, ice, and other debris that could impair latch performance.
- Protruding Fasteners: Grind or remove any protruding fasteners after installation.
Additional Considerations
The MagnaLatch system can be used on swimming pool gates and other child safety barriers. It is recommended to install safety barriers at least 1 meter (approximately 3.3 feet) from the edge of the water. For private pools, it is recommended not to install the barrier too far from the pool to maintain its effectiveness. When installing on steel or vinyl with metal inserts, pre-drilling holes is advisable to prevent screw breakage. The documentation also notes that the system is designed for use on family or collective swimming pool gates.
Conclusion
The D&D Technologies MagnaLatch 3 Series Top Pull model provides a latching solution for gates and barriers, particularly those requiring enhanced safety features like those found around swimming pools. Correct installation, adhering to local codes and regulations, is paramount. Regular maintenance, including key removal, appropriate lubrication, and debris removal, will ensure long-term reliable operation. It is vital to remember that this latch is a safety device and should not be considered a substitute for responsible adult supervision. The documentation provides conflicting details regarding specific height requirements, so consulting local authorities is essential.
