Ridgid installer is an excellent multifunctional plumbing tool for under-sink work. Its serrated edges grip plastic sink nuts and supply lines with 2, 3, 4, and 6 tabs measuring 7/8" and 1", making tightening and removal effortless. The extra-long design is ideal for hard-to-reach areas such as faucets, sprayers, and ball valves. The shut-off valve turns difficult-to-access angle stops without damaging chrome, while the open slot allows easy access to existing supply lines. The opposite end features a mount that holds the drain assembly in place during strainer nut removal or installation. The lightweight, high-strength plastic construction with durable aluminum inserts is built for long-lasting use.
