THEY LOCK IN PLACE: With patented Snap-Tite Technology, PegPro hooks lock securely onto your pegboard. Hooks never fall out or wobble when you remove your items. They are simple to remove so reorganize your storage system whenever you want. COMPATIBLE WITH 99% OF PEGBOARDS: PegPro works with standard board thicknesses commonly available in big box & local hardware stores. If your board is thinner than 4 stacked dimes or 3 stacked nickels (7/32 in, 5.5 mm) it will work with our hooks! | MULTIPLE COLORS, SHAPES AND SETS TO KEEP THINGS ORGANIZED: Includes 24 Snap-Tite Grommets. Whether you’re organizing your garage, workshop, laundry room or arts and crafts accessories, you’ll always find the perfect colors and multifunctional shapes to keep things neat, tidy and there when you need them. Having a variety of colors and shapes helps you apply 5S/lean manufacturing principles in your factory, office, or home. | EXTREMELY HIGH QUALITY MATERIALS AND MANUFACTURING: These heavy duty hooks are precisely molded from tough, fiber-reinforced, engineering-grade plastics, so they are sturdy enough to hold heavy attachments like power tools. They hold up great, even under constant use, but they will not scratch or mar your delicate items. | DESIGNED TO NEVER DAMAGE YOUR PEGBOARD: We’ve designed these hooks with a clever fail-safe mechanism. If you hang too much weight, the hook will break – not your pegboard. And unlike metal hooks, the plastic locking system won’t scratch up your pegboard during installation. | 100% MONEY BACK GUARANTEE AND MADE IN THE USA: These hooks are proudly made in the USA using the same quality control system we use to manufacture parts for Honda, Toyota, and Lexus. That’s why we’re confident enough to let you try them risk free. If you aren’t totally satisfied, then just send them back to us for a full and immediate refund. (Even if our hooks were not compatible with your board thickness, we will still give you a 100% refund, no questions asked!)
