Base frame: Rectangular profile 80x40 mm. Design: Standard profile groove. Freestanding gates can be easily and conveniently transported without much effort. Usable with all freestanding gates that have a base frame made of oval profile 120/100 mm, square profile 80x80 mm, or rectangular profile 80x40 mm. Made of aluminum with air-filled wheels with a diameter of 200 mm. Simply screw onto the rear bottom tube of the gate. To transport, tilt the gate slightly backward. Also suitable as a retrofit kit for existing gates. The set consists of 2 transport wheels for 1 gate. Note: The base frames of gates differ in profile shape (oval, square, rectangular) and in the type of profile groove. The profile groove is the recess where the net is attached with net holders. Depending on the type of net attachment, they are equipped with either a standard or a deep profile groove. In gates with a standard groove, the net holders protrude from the profile, while in a deep groove, the net holders are recessed and do not extend beyond the edge of the profile.
