Stanley Bostitch 15-Degree 1-3/4-in. Coil Roofing Nailer (RN46-1)

Key Features

Light on the Roof

The magnesium housing helps keep weight down to 4.9 lbs while still holding up to jobsite use. That matters when you are moving fast across a roof and firing all day.

Fast Reloads

The single-action side-load canister and 120-nail magazine cut reload time. Less fiddling with the coil means more shingles down before you climb off the roof.

Roofing Nailer Control

Tool-free depth control, an adjustable shingle guide, and zero nail lockout help this coil roofing nailer place fasteners where you want them and tell you when it is time to reload.

Overview

The Bostitch RN46-1 Coil Roofing Nailer is a 15 degree pneumatic roofing nailer built for installing shingles, roofing panels, and similar exterior materials. This is a roofing nailer designed for fast, repeatable fastening on roof work where speed, consistent depth, and lighter weight matter. Model Number: RN46-1. If you need a dedicated air-powered nailer for roofing instead of a general framing or finish gun, this is the right category of tool.

What stands out right away is how the RN46-1 is set up for production work. It runs on standard pneumatic power with a required operating pressure of 70 PSI and a maximum of 120 PSI, and it feeds from a coil magazine that holds up to 120 nails. That combination is a good fit for roofing because it keeps reloads down and keeps the tool compact enough to move around tight roof areas without feeling bulky.

Bostitch kept the weight to 4.9 lbs and used a magnesium housing for jobsite durability without making the tool a brick in your hand. When you are working overhead, reaching across courses, or spending hours on a steep pitch, that lighter build is not just a comfort feature. It directly affects fatigue and control. The overmolded grip also helps when your hands are dusty, gloved, or just putting in a long day.

On the performance side, the RN46-1 is designed around the stuff roofers actually care about: depth consistency, reload speed, and not beating up the tool on abrasive surfaces. The quick-set adjustable depth guide lets you tune nail set quickly as material or conditions change. The patented single-action side-load canister makes reloading faster and simpler than fussing with slower magazine designs, and the zero nail lockout helps prevent dry firing while also giving you a clear signal that it is time to load another coil.

Bostitch also added details that matter over time, not just on day one. The nosepiece uses carbide inserts for longer life, and the aggressive wear guards and skid pads help protect the tool when it is getting dragged across shingles and other rough surfaces. Those are the kinds of features that make sense on a roofing nailer because roof work is hard on tools. The aluminum housing and durable construction back that up for crews who expect a gun to stay in rotation.
