UNIMAC CLS400 20-50mm 16ga Cordless Finishing Nail Gun Kit

Product Overview

The UNIMAC CLS400 is a practical cordless finishing nail gun built for people who want cleaner, quicker fastening without dragging around an air hose or compressor.
It is designed to make trim work, light carpentry, and general finishing jobs feel faster and more convenient while still giving you the control needed for neater results.

Why This Nailer Stands Out

What makes the CLS400 especially appealing is the way it combines cordless freedom with practical finishing features.
Instead of being tied to a bulky pneumatic setup, you get a compact battery-powered nailer that is easier to carry, easier to position, and much more convenient for moving around the job.

Cordless 20V Freedom

One of the biggest advantages of this nailer is its cordless 20V lithium-ion design.
That means no compressor noise, no air hose tangles, and no waiting around to get a separate air setup ready before you can start working.

Designed for 16 Gauge Finish Nails

The CLS400 is built for 16 gauge straight finish nails, making it a practical option for the kind of work where you want solid holding power with a cleaner, more professional-looking finish.

Useful Nail Length Range

With support for nails from 15mm through to 50mm, this nailer gives you good flexibility across lighter trim work, panelling, mouldings, and other common finishing jobs.

Fast Firing Rate for Smoother Workflow

The listed cycle rate of one nail per second helps keep work moving at a steady pace.
It is quick enough to feel efficient on repetitive jobs without making the tool feel rushed or hard to control.

100-Piece Magazine Capacity

The 100-piece nail capacity is another genuinely useful feature.
It helps reduce the need for constant reloading, which makes a noticeable difference when you are working through a longer run of trim or repeated fastening tasks.

Up to 400 Shots Per Charge

The product highlights note up to 400 shots per charge, which adds to the tool’s appeal for mobile work and general convenience.
It is the sort of battery performance that helps make a cordless nailer feel truly practical rather than just convenient in theory.

Quick-Release Magazine with Viewing Window

The quick-release 100-piece magazine and nail viewing window are thoughtful practical touches.
They make loading simpler and help you keep an eye on remaining nails before the tool runs empty at the wrong moment.

Depth Adjustor for Cleaner Finishes

A strong feature of the CLS400 is its depth adjustor.
This gives you more control over how the nails sit in the material, which is especially important when you want cleaner finishing work rather than a rough, inconsistent result.

No-Mar Tip for Better Surface Protection

The included No-Mar contact tip adds another level of polish to the setup.
It is designed to help reduce surface marking, which makes the tool especially useful on visible trim and finishing work where the final appearance matters.

LED Alerts and Dual Work Lights

UNIMAC has added a helpful set of user-friendly features here, including LED alerts for jams, empty loads, and battery status, along with dual LED work lights for better visibility in darker areas.
These details can make a real difference in day-to-day use.

Safety and Anti-Dry Fire Protection

The safety switch and anti-dry fire system add reassurance during use.
They help the tool feel more practical and better thought out for regular work, especially when speed and convenience are important but control still matters.

Complete Kit Ready to Go

This is not just a bare tool. You get the nailer, a 20V lithium-ion battery, charger, carry case, spare No-Mar tip, and starter nails in the box, which makes it much easier to get to work straight away.
