Set of two extendable supports with crank and ProPlus 361500 mounting for 1000kg flatbed trailer 290-460mm
The ProPlus 361500 Set of Two Extendable Support Legs with Crank and Mounting Hardware is a practical solution for stabilizing your trailer, flatbed, camper, or other vehicle while parked. The sturdy supports help keep your vehicle stable and reduce sway caused by wind, interior movement, or uneven surfaces. The included crank handle allows for convenient extension and retraction of the supports.
The supports can be mounted to appropriately adapted frame or chassis components, depending on the vehicle's design. For vehicles equipped with side beams to which the support can be bolted, use the included mounting hardware. The 8.5 x 8.5 cm feet provide stable support. The set is ideal for parking, loading, unloading, and everyday use of a trailer, flatbed, or camper.
The set includes:
- 2x extendable support
- 1x crank
- 2x mounting plates
- mounting elements (screws, nuts)

Permissible load
The maximum load capacity of each support leg is 500 kg , ensuring stable support for the vehicle when parked. Using two supports effectively limits the swaying of the camper or trailer caused by wind or movement within the vehicle. The supports should only be used for stabilization purposes, not as a jack for servicing under the vehicle.

Extension length
The 170 mm extension length of the support allows for convenient adjustment of the support height to suit various ground conditions and trailer designs. The support's adjustment range is from 290 mm to 460 mm , allowing for stable positioning of the camper or trailer when parked, reducing sway and improving comfort .

Crank
The extendable supports are operated using the included 850 mm long crank with a 17 mm wrench size , which allows for convenient raising and lowering of the support. This provides simple and precise height adjustment and stable support for the trailer when parked. This allows the support to be easily extended and retracted, allowing for quick and convenient preparation of the trailer for parking or driving.

Anti-corrosion protection
The supports and crank are made from a combination of steel, PA plastic, and zinc alloy, ensuring durability, stability, and resistance to everyday use . The steel structure provides strength and reliable support for the trailer, while PA plastic and zinc alloy components improve functionality and resistance to wear. The materials used make the set suitable for outdoor use , where the supports are exposed to moisture, dirt, and changing weather conditions.
Extendable crank supports are a practical trailer accessory used to stabilize the trailer during parking, loading, and use . Height adjustment is achieved using a crank, allowing for easy and precise adjustment of the support to the ground. They provide reliable structural support, reduce tilt, and increase safety around the trailer. They are most often mounted at the rear of the frame and help maintain stability, especially when the trailer is not connected to a vehicle. They are not designed to lift a loaded trailer , but rather to provide stable support. This practical solution is used on transport trailers, boat trailers, and caravans, improving comfort and safety.
