Bretford’s Legacy Shelves attach using four solid steel pins. Shelves are easy to adjust by simply removing the shelf and relocating the shelf pins. Our shelving has a unique Tamper Proof Pin System that prevents the pins from becoming dislodged. For safety purposes, shelf pins have a center collar making the pins impossible to pull out once the shelf is installed. Steel flat shelves feature an integrated bookstop. An 18-gauge stiffener also acts as a book support channel. Each shelf is able to support 150 pounds with zero deflection. Available in all standard power paints.
