Best of all: in addition to the 18V battery pack, Ryobi has incorporated a 120V power option. This means that you can preserve your battery packs by plugging your work light into household current, when available. The light is full, white, and very bright, plus the operation is simple. The battery pack snaps firmly in place in the back. If you remove the pack, your extension cord (not provided) fits in the adjacent port. Of all the numbers associated with this Ryobi tool’s specs, the important one is 15. This 18V cordless tool, operating from the ONE+ platform, drives substantially heavy finish nails that are 15-gauge. Fifteen gauge is a magic number because it allows you to lengthen the nails up to 2-1/2 inches. This product is a boon for any homeowner who would never think of buying a power nailer because of bulky compressors, canisters, or hoses. Rather, the Ryobi 18V ONE+ Angled Finish Nailer draws all of its power from the attached battery pack, and this power creates the air compression required to drive the nails. The Ryobi PEX Crimp Ring Press Tool accommodates 3/8-inch, 1/2-inch, 3/4-inch, and 1-inch pipe sizes. Using an electric crimping tool such as the Ryobi instead of a manual crimper means that you can hold the tool steady while the crimper closes shut. Within five seconds, the perfectly calibrated compression happens, rewarding you with an LED light that lets you know that you can move onto the next fitting. While the Ryobi ONE+ 18V PEX Crimp Ring Press Tool is firmly a niche product, it will pay for itself many times over by saving you on the cost of a plumber’s visit.
