Buyers Products DH300 Aluminum Door Hold Back

The DH300 uses a 2-inch hook with a spring-loaded latch and a keeper, making it compact yet functional for smaller trailers. Best for buyers who need a simple, quick-access hold open without bulk. The aluminum construction helps resist corrosion in outdoor environments. A potential limitation is the smaller hook size, which may not fit oversized doors on some trailer models.
Buyers Products DH304 Aluminum Door Hold Back

The DH304 expands to a 4-inch hook, offering stronger hold for larger trailer doors. This is better for enclosed trailers or doors that experience more wind or frequent opening. The spring-loaded latch and keeper provide secure retention. Best for operators who need a more robust hold and predictable operation, though it is larger and heavier than the DH300.
6 Inch Heavy Duty Aluminum RV Door Catch

This option features a windproof, rustproof ball socket design designed to firmly secure doors in open or partially open positions. It is suited for campers, cargo trailers, sheds, or RVs needing a durable hold for frequent door adjustments. A potential caveat is that the 6-inch length might be excessive for small trailers, so measure door clearance before purchasing.
Hicarer 8 Sets Trailer Door Holder Kit

The Hicarer kit provides eight components with a low-profile bumper holder, making it versatile for multiple doors or configurations on a single trailer. Best for budget-conscious buyers or those installing several holdbacks across a fleet. The set’s variety supports customization, but assembly might require more effort than single-holdback options.
ProCamp 10″ Black Trailer Door Holdback

The ProCamp holdback uses a heavy-duty powder-coated aluminum ball-socket design for corrosion resistance. It is a good match for trailers used in harsh weather or frequent outdoor exposure. It is best for buyers who value a robust, long-lasting finish; avoid if you need a lighter, less conspicuous option for smaller doors.
Buying Guide
What size do you need? Consider door width and weight; a 2-inch or 4-inch hook suits most mid-size trailers, while 6 to 10 inches are better for larger or frequently opened doors.
What material matters? Aluminum offers light weight and corrosion resistance; steel is tougher but heavier and prone to rust without coatings.
How will it be used? If you routinely load and unload with wind or in outdoor conditions, a spring-loaded latch and a keeper provide consistent performance.
Mounting and compatibility: Check hole patterns, screw sizes, and whether your trailer doors require a ball-socket or simple hook-and-keeper design.
Durability vs. install effort: Higher-end models may offer easier operation and longer life, but could require more initial setup. Choose based on how often you use the door and the driving conditions you face.
