Upgrade your kitchen cabinets with this sturdy sliding wire basket system. The key to this system is an extending ball-bearing system that allows you to smoothly pull out what you need. The system is strong enough to hold up to 100 pounds, making it a great way to hold heavier appliances that would otherwise be difficult to pull out of a cabinet. This sturdy 2-tier wire basket has an 18-inch depth to maximize storage space. It easily installs into most 12-inch cabinets with an 8.5-inch opening to simplify storing pots, pans, lids, bottles, or other kitchen supplies. To install the basket system, all you have to do is drill 4 screws to connect the base of the system to the bottom of your cabinet. All of the required mounting hardware is included (optional cabinet door mounting kit, 5WB-DMKIT, sold separately). Double check your cabinet's opening to allow the best fit. Measure side to side, front to back, and top to bottom. Double check to make sure your product is within measurements and don't forget to take into account any obstructions.
