Black Bull shelf protection boards B, dimensions HxW 500 x 190 mm, extendable up to 1300 mm. It redirects the majority of laterally applied forces through the rollers. It protects the floor and increases durability. Usable for all shelf widths (width adjustable). It reliably absorbs impacts. The special design of the impact protection angles allows for the lateral insertion of two steel boards with a C-profile. The 300 mm wide protection angles allow for the shifting of the boards by up to 200 mm per protection angle. Thus, each board set can be individually adjusted in width by up to 400 mm. A board set B consists of two impact protection angles (500 x 300 x 190 mm, 4 mm material thickness), two boards (100 x 40 x 3 mm), and four clamping pieces.
