No matter whether it is a garage door for your house, a storage facility in a commercial environment or an industrial building, a single lock on the garage door is never sufficient security. Traditional single point locking systems have their weaknesses in that the corner opposite the lock can be flexed away or prying force could disengage the latch, or spread apart the garage door frame. Multi-point locks correct these issues by simultaneously engaging more than one bolt or rod. However, not all multi-point lock kits operate equally. Their efficiency is achieved through engineering precision in their smooth operation, positive engagement, and required maintenance levels. Here are 4 ways the latest in garage door lock kits boost multi-point locking efficiency:
1. Synchronized Rod Transmission for Effortless Operation
The number one complaint from customers about traditional multi-point locks is their "clunky", "gritty", and "hard to turn". A lack of synchronized rod operation forces one or more locks to engage first, thus creating resistance and wear on the moving parts. Modern multi-point locking systems utilize precision-machined gears or linkage mechanisms that force every locking rod simultaneously with equal force.
MeiGu Lock Industry Co., Ltd. (WenZhou) has fine-tuned this system through their swing handle and rod control products. The rotation of the swing handle drives a central gear hub with hardened steel pins to simultaneously transmit rotation to both the upper and lower rods. The gear ratio is designed to transmit the rotation to allow full rod extension (normally 20-30mm of throw) with a quarter-turn of the handle. The synchronized motion allows the rod ends to smoothly enter the locking receivers without excessive force. With doors that must be opened and closed many dozens of times a day (like in an industrial workshop or storeroom), efficient, single-handed operation will save on operator fatigue and prevent premature wear on the system components. With precise, CNC-machined gears and die cast zinc housing, MeiGu ensures alignment and a durable locking mechanism even after thousands of cycles.
2. Optimized Rod Guides and Low-Friction Bearings
The success of a multi-point locking mechanism relies heavily on its guidance components. Each of the locking rods must move within an opening or bracket in the garage door. Without friction-free guides, the locks will be extremely difficult to operate. High quality multi-point lock kits use self-lubricating bearings or low-friction materials to avoid these binding problems.
The MeiGu rod control systems make use of acetal or nylon guide bushings on the interior portion of the garage door opening. They provide a smooth sliding interface between the steel rods and the support bracket, reducing friction even in dusty environments. The guide brackets also provide 2mm of adjustability to account for sagging or misalignment of the door frame or the door itself. For highly specialized environments, MeiGu offers rolling guides instead of the bushings; these utilize hardened steel balls between two rings for an almost friction free operation. Together with hardened steel rods, precision-ground to a smooth surface finish, the locks open with almost no effort for the lifetime of the door. Efficiency means reliability in the real world, not just when the lock is in good condition.
3. Positive Engagement Indicators and Adjustable Strike Plates
Even with a well-designed multi-point locking system, users do not want to doubt if all of the locking bolts are engaged. A common concern with these systems is if one bolt has extended less than the other; this means a less secure closure. Modern systems prevent these issues through built-in indication mechanisms and fully adjustable strike plates.
MeiGu Lock Industry Co., Ltd. Incorporates positive locking feedback into their cylindrical and cam multi-point locks that makes a distinctive "click" when each final locking bolt engages properly into its strike plate receiver. Swing handle activated systems often utilize a detent position that resists unintentional retraction of the swing handle. MeiGu also sells fully adjustable strike plates (in their hook/accessory range) so that the locking bolt can be set so that it enters its receiver a certain depth each time (typically 12-15mm). Too short means that not enough force will be applied to prevent prying, and too long means that the strike plates could be slightly bent. With all of the points engaged on the first try, users can be assured of the security of the door, and no extra maintenance visits are required for proper adjustment.
4. Modular Configurations for Different Door Types and Sizes
Not all garage doors are the same size or use similar materials. A two-meter wide residential garage door and a four-meter wide commercial garage door are vastly different and require a system that fits the particular setup. Traditional, non-modular systems are often designed for one application and will need compromise, potentially compromising efficiency, in others. The best systems on the market today allow customization through various components, lengths and number of locking points.
The MeiGu range of swing handle and rod control systems offers exactly this flexibility. It can be ordered with two, three, or four locking points (depending on needs), using extension rods made from stainless steel or zinc-plated steel. In some instances, it may be preferable to use a compact cam lock on an auxiliary bolt for a narrower door style. Even with visible, surface-mounted hooks in MeiGu's hook/accessory line for heavier wooden garage doors, the efficiency is comparable to mortise applications. They offer a full CAD design and mold-making service for specialized multi-point locking systems (which they have already used to complete over 500 projects for clients in North America, Europe and Southeast Asia). Any MeiGu system can be custom fitted for your application for maximum efficiency.
Conclusion
Efficiency in multi-point locking systems comes down to synchronized motion, minimal friction during rod transit, immediate feedback for users, and customizable designs for all applications. Garage door lock kits from MeiGu Lock Industry Co., Ltd. offer a level of design and engineering that delivers efficiency in all four of these key areas by combining 15+ years of CNC machining and die-casting experience with an intuitive understanding of end-user needs.
