GREX H850LX 21 GA 2" Brad Nailer - H850LX

GREX H850LX 21 GA 2" Brad Nailer - H850LX

Grex's new H850LX 2" 21 gauge brad nailer draws from over 16 years of experience designing and manufacturing the worlds best 23 gauge headless pinners that pros have relied on. 21 gauge nails offers a middle ground between the small holes size left by a 23 gauge pin and the holding strength of an 18 gauge brad nail. The H850LX is equipped with all the newest features found in Grex tools including the first to include an integrated edge guide. And its built with the same all metal design and quality that Grex continues to be recognized for.

The adjustable on-board Edge Guide enables you to work faster and with more precision when assembling drawer boxes, cabinets boxes or similar. Drive nails at a consistent distance from a referenced edge. Its easy to adjust, set and operate. When not needed, the Edge Guide can be conveniently directly stored on the tool for convenient access when needed.

The Auto Lock-Out features a new patent pending One-Touch Over-Ride. Now tack or finish a project using the 7 “reserve” nails with one touch to the One-Touch Over-Ride button.

Auto Lock-Out was added to prevent dry-firing and to assist in difficult, more critical jobs such as overhead crown molding. Dry-firing can cause damage to the tool and might cause damage to an exquisite, expensive project. To prevent dry-firing, the Auto Lock-Out locks the GREX H850LX with approximately 7 nails remaining in the magazine. High up on a ladder fastening overhead, with a single touch, press the One-Touch Over-Ride button and safely use the remaining pins to tack a project-piece in place.

What’s more, the high tolerance precision machined hardened steel driver, Posit-Lock nose cover and nose guide assembly aligns and seats the nails for optimal drive performance. What is Posit-Lock- it's tight tolerance, durability and functionality that reduces jams to a minimum.

GREX, demanded by Pros, for more than 20 years has helped professionals rise to the top of their trade. Now explore.
