Ganland GL-13123S stainless steel refrigerated truck rear door lock is a heavy-duty, precision-engineered hardware component designed to provide secure, reliable latching for the heavy doors of refrigerated trailers and insulated transport vehicles. As an essential part of a vehicle's cargo containment and security system, this lock is specifically engineered to withstand the constant vibration, extreme temperature fluctuations, and harsh environmental conditions associated with cold-chain logistics. Its robust stainless steel construction and functional design make it an ideal replacement part for fleet maintenance, offering a perfect balance of security, durability, and ease of operation
The foundation of the GL-13123S is its solid, high-grade stainless steel construction. This material is chosen for its exceptional strength and superior corrosion resistance, ensuring that the lock will not rust or degrade even when exposed to constant moisture, condensation, and the chemical cleaning agents used in refrigerated transport. The lock features a heavy-duty, two-part design consisting of a mounting bracket and a pivoting latch arm. The mounting bracket is engineered with a reinforced, double-walled hinge point that houses a sturdy pivot pin. This robust pivot mechanism allows the latch arm to swing smoothly and engage with a corresponding striker plate, creating a secure, positive lock that prevents the rear doors from opening accidentally during transit.
A defining feature of this assembly is its integrated, multi-point mounting design. The base plate of the bracket features pre-drilled, countersunk holes that allow for quick and secure installation using standard bolts or rivets. The countersunk design ensures that the fastener heads sit flush with the bracket surface, preventing snags and providing a clean, professional appearance. The latch arm itself features a distinctive, elongated U-shaped slot. This slot is designed to receive a heavy-duty striker bar or pin, allowing for a degree of vertical adjustment during installation. This ensures that the lock can be perfectly aligned with the door frame, guaranteeing a snug, rattle-free fit even if the door sags slightly over time.
The accompanying technical diagram highlights the precise engineering tolerances of the GL-13123S, noting a total length of 165mm, a width of 62mm, and a material thickness of 4mm. The mounting base features five 7mm holes for secure fastening, while the latch arm includes an 80mm slot and a 46mm internal opening. These precise dimensions guarantee compatibility with standard refrigerated trailer door systems, making this lock an ideal replacement part for maintenance and repair. The polished stainless steel finish also provides a clean, hygienic appearance, which is essential for vehicles transporting food, pharmaceuticals, and other temperature-sensitive goods.
By combining robust stainless steel materials, a corrosion-resistant finish, and a functional pivot-and-slot design, the Ganland GL-13123S offers unmatched reliability and operational convenience. It ensures that rear doors remain securely locked, protecting valuable cargo and preventing unauthorized access. Its straightforward installation and durable construction make it a practical and highly effective solution for maintaining the security and operational efficiency of refrigerated vehicles and industrial equipment. Whether used for new builds or as a direct replacement for worn-out locks, this rear door lock delivers dependable, long-lasting performance.
