Crown staplers are utility players. They can be used to fasten countertop blanks, detail work where the project will be covered, and prefab work to produce a higher-quality, lighter, and easier-to-build and -install products. They also nail together plywood and small blocks that would otherwise go to waste.

Senco’s latest crown stapler model, the SLS150Mg, is air-powered and lightweight. It features a magnesium body and weighs in at 2.6 lbs. With no recovery between staples, it is a good fit for high-volume shots in applications such as cabinets, furniture, casegoods, door or windows and millwork.

The SLS150Mg accepts ½Ë to 1-9/16˝ 18-gauge, ¼Ë crown staples, so it can be used on both internal and external trim, furniture, and for cabinetry or other finished applications. (In FAQs Senco explains how to staple Knape & Vogt shelf standards with staples.)

Air-powered tools exhaust air with each shot, but the SLS150Mg’s oil-free motor, and a 360° adjustable exhaust port help keep dust, debris and oil off the work surface and away from the user. A swivel air inlet reduces tangled hoses and a rotatable belt hook lets you keep the tool at your side when not in use, keeping projects free from accidental dings.

A switch lets you do bump fire actuation for quick stapling, if precise hits aren’t required. Flipping a switch transitions to sequential fire. (In sequential firing, it staples once with each trigger pull; in bump firing, the trigger is held in and the gun nose (it has a no-mar tip) is bumped on the target staple point.

A nose-mounted light helps with staple placement. A reload indicator eliminates firing when staples run out; a thumbwheel adjusts the drive depth for wood hardness or varying density, for holding power based on the application.
