Container House Door Lock Accessories

Container house door lock accessories mainly include lock heads, lock bases, brackets, bushings, door handles, handle bases, cup washers, locating rings, lock rods, and other components. Some also include lock catches, upper handle catches, lower handle catches, etc., with slight differences depending on the product model and manufacturer design.

1. Basic Component Composition
Most container door lock accessories are sold in sets, with each set typically including:

• Core Lock Components: 1 left lock head, 1 right lock base (some models like LD8901 may have one on each side);
• Support Structure: 2 large brackets (with bushings), 1-2 small brackets (with small bushings), used to fix the lock rod and distribute the weight of the door panel;
• Operating Components: 1 door handle, 1 handle base, with some products adding lock catches or push-bar escape locks (such as for energy storage compartment protective doors);
• Auxiliary Components: Cup washers, 4-8 locating rings (used to stabilize the movement path of the lock rod).
  For example, the products from Cangzhou Xinhe Container Manufacturing Co., Ltd. include the above standard components in each set, with a unit weight of 5 kilograms, and each container requires 4 sets.

2. Special Models and Customization

• 1-inch Door Lock Accessories: The LD8901 model from Tianjin Jinbin Huaxing Mechanical Accessories Co., Ltd. is clearly marked as suitable for 1-inch container doors, with a more detailed list of accessories including upper handle catches and lower handle catches, weighing 5.5 kilograms per set;
• Separate Quotation for Lock Rods: The length of the lock rod needs to be customized according to the size of the container, so most manufacturers (such as Cangzhou Xinhe and Jiaxing Shilong) list it as an optional accessory and quote based on actual needs;
• Functional Expansion: Brands like Kustik design multi-point locking mechanisms for protective doors, increasing the number of locking points to resist wind pressure and equipping them with Class C anti-theft lock cores to enhance security.

3. Materials and Craftsmanship

• Main Materials: Lock heads, lock bases, and door handles are mostly made of forged steel, brackets are stamped parts, and bushings are injection-molded parts, ensuring strength and corrosion resistance;
• Surface Treatment: Outdoor hardware (such as hinges and locks) needs to be galvanized or treated with stainless steel. In coastal environments, 316 stainless steel must be used to prevent rusting;
• Assembly Process: Lock boxes and lock rod guide bases need to be welded with reinforcing pads, and the guide grooves need to be polished flat to ensure smooth movement of the lock rod without jamming.

4. Procurement and Adaptation Recommendations

• Quantity Calculation: Standard containers usually require 4 sets of door lock accessories (if including lock rods, the length needs to be calculated separately);
• Manufacturer Selection: Prioritize manufacturers that have passed ISO9001 certification and possess classification society certificates (such as American ABS and French BV), such as Jiaxing Shilong and Zhongxin Container;
• Customization Needs: For special sizes or materials (such as aluminum alloy), contact the manufacturer for customization. Enterprises like Zhongxin Container can undertake non-standard designs.
