Version: For the Ultimate trampoline. The base plate for large trampolines ensures high stability even on springy gym floors. The plates increase the contact area, so the high pressure from jumping does not affect the elastic floor. This helps to avoid disruptive vibrations. The base plate has a non-slip underside. Even slight shifts are no longer possible - even under high loads in competitive sports. The base plates for large trampolines are available individually and in sets of four. Product details: Plates made of multiple glued plywood, cutout for floor protector attachment, non-slip underside, total weight: 4 kg, dimensions (LxWxH): 50x50x3 cm.
