When you work 10-12 hours a day, it’s crucial to use lightweight and properly balanced tools. Holding and maneuvering heavy hand-tools brings unnecessary fatigue, pain, and stress on the muscles and eventually on the entire body.

MAX Roofing Nailer Comes With Adjustable Depth Control

It comes with an adjustable dial depth control, making it easy to adjust how deep or shallow you want to drive the nails: from flush, shallow and countersink.

For best performance, accuracy, and work-quality, it’s crucial to have this easy-to-adjust depth of drive feature.

Rapid Fire Trigger

It has a rapid-fire trigger that allows you to drive nails fast an easy. This is how it works: you hold the trigger and every time the tip bumps the work surface it drives a nail.

Due to the good balance, you can drive the nails fast with accuracy, letting you fire the nails in the right place every time.

The Secret of “almost” no Jamming: Magnetic Nose Feature

One of the most annoying things that can happen when you’re actively driving nails and trying to the job done is jamming. This tool almost never jams, and that’s a huge plus for a roofing nailer.

MAX designed the CN445R3 to prevent jamming as much as possible, by adding the magnetic nose. Because of the magnetic nose feature, the last nail of the coil remains in place without making the tool to jam. This allows you to drive the last nail with accuracy and without any problems.

Shingle Guide

All roofing nailers should be roofing friendly. That means that they should be designed to make the roofer’s job easier. The nailer comes with a handy shingle (see also ‘How Many Shingles In A Bundle‘) guide to help you align the shingles precisely every time.

Magazine Layout, Capacity and Nails

Max CN445R3 SuperRoofer comes with a side-loaded magazine, that’s easy to release and close.

The magazine can hold 120 coil nails, with a minimum size of 3/4 inch (19mm) and a maximum size of 1-3/4 inch (45mm). The nail shank diameter allowed is 0.12 inch (3mm).

The magazine is easy and comfortable to reload. This nailer accommodates the most common range of nail sizes used for roofing.

Trigger Lockout Feature: Never shoot blanks

The MAX nailer comes with a trigger lockout feature, that prevents the nailer from firing when the magazine gets empty.

This is a smart and important feature, that can increase your productivity and work-speed. When a nailer doesn’t come with a lockout feature, you can end up firing blanks without knowing. It is extremely frustrating to shoot blanks, look back and realizing no nails were driven.
