Once upon a time, when pneumatic nailers were all the same — to me at least — this fine tool would’ve escaped my attention. This is a multi-blow nailer, which means there’s no depth adjustment; you simply hold the actuator until the nail is driven to the depth desired. If you hit a knot, just hold the actuator longer.
You trigger the actuator by simply pushing the nail head against the target while holding the handle. The pictured GR150 joist hanger nailer weighs just 4.4 lbs, a wee bit lighter than the Bostich StrapShot, and drives 1-1/2″ nails, perfect for working with 90% of joists and joist hangers. The GR250 will work with 1-1/2″ or 2-1/2″ nails and weighs just a little more at 4.8 lbs. Both expose the nail head for accurate nail placement in the metal hanger holes.
You can download parts diagrams and parts lists from Grip-Rite’s site, and they sell driver assembly kits and rebuild kits that contain the most common sets of parts — Grip-Rite makes it really easy to own and service these nailers.
Street pricing on the GR150 runs a little over $220, but Home Depot has it for $190.
