The Z-cutter is a specialized device designed to precisely and consistently cut pre-formed Z-closures, essential for locking ridge caps onto metal roofs. These closures need to be accurately sized to match specific panel widths.
The Z-cutter complements common metal-folding machinery (such as standard 10-foot brakes), allowing contractors to efficiently utilize leftover trim pieces to create Z-closures, reducing waste and maximizing material efficiency.
The Z-cutter can cut 26-gauge and 24-gauge steel, and .032 and .040 aluminum.

The Z-cutter comes in three main components:
Assembly is straightforward, typically requiring only a 3/16″ Allen wrench for handle installation. Quick-adjust knobs allow you to set the cutting length accurately and quickly, while their unique spring-loaded design ensures they never obstruct the operator’s workspace.
While the Z-cutter is primarily intended for standard-length Z-closures (1”, 1.5” and 2” in height), it can also handle occasional specialty cuts, such as longer closures for steep hip angles, without sacrificing accuracy. Its compact, robust design makes it easy to integrate into existing setups and transport between job sites.

Cutting Z-closures traditionally involves marking each piece individually, cutting manually with snips, or using abrasive tools and saws. This can take hours and prolong your roofing project. The Z-cutter enables contractors to complete the same task in a fraction of the usual time.
Manual cutting demands meticulous measurement, increasing labor costs. The Z-cutter simplifies the process, allowing fewer workers to produce better, more consistent results, saving thousands in labor expenses over the life of your projects.
Unlike abrasive cutting methods, which can void warranties on painted finishes due to heat and friction, the Z-cutter delivers clean cuts without compromising material integrity. This preserves the manufacturer’s warranty, providing peace of mind to contractors and homeowners alike.
The Z-cutter by New Tech Machinery is designed specifically with contractors’ needs in mind—saving you time, reducing labor costs, and consistently producing high-quality Z-closures. By streamlining the cutting process, this accessory empowers you to deliver faster, more reliable results, enhancing your overall productivity and profitability
