Air staplers for upholstery and trim use different fasteners, even when the tools look similar. Before comparing brands, identify the staple series, wire gauge, crown width and leg length required for the work. Buying the wrong family of staples can leave you with a tool that cannot use your supplies.
The two manufacturer-documented examples below show the difference between fine-wire upholstery fastening and narrow-crown woodwork. They are buying references rather than winners from our own hands-on testing.

1. Match air staplers to the staple specification
The PORTER-CABLE US58 uses 22-gauge staples with a 3/8-inch crown and leg lengths from 1/4 to 5/8 inch. Its one-inch nose extension helps reach limited-clearance fastening locations, and its bottom-loading magazine holds 185 staples.
That specification is different from an 18-gauge trim staple. Crown width alone does not establish compatibility: check the exact approved staple family as well as its gauge and length. Keep the box label with your supplies so replacements are easy to identify.
2. Choose a trim stapler for compatible woodwork
The PORTER-CABLE NS150C drives 18-gauge, 1/4-inch-crown staples from 1/2 to 1-1/2 inches long. It has a sequential-style trigger, a tool-free depth adjustment and a removable nose tip. Its kit includes a case and an air fitting.
These air staplers are not interchangeable simply because both drive staples. Select the fastener for the material, required attachment and finished appearance. Do not assume a wider crown always provides a stronger joint; the substrate, staple penetration and overall fastening design also matter.
3. Test depth on matching scrap
Use an offcut or concealed test assembly that matches the material layers and backing. Inspect both the staple seating and the opposite side before working on the finished piece. A tool setting that works in one material may need adjustment for another.
Air staplers differ in their controls. The NS150C has a mechanical depth adjustment, but that feature should not be assumed for every upholstery model. Follow the individual manual for pressure and adjustment procedures, and never exceed the tool’s permitted operating range.
4. Check handling and maintenance
Compare nose access, hose position, balance and magazine loading. For a chair frame, getting the nose into a recess may matter more than maximum capacity. For repeated trim work, consider how easily you can see the fastening location and monitor remaining staples.
Maintenance requirements also differ between air staplers. The US58 package includes oil, while the NS150C lists a maintenance-free motor. Follow each manual rather than applying a single oiling routine to every pneumatic tool. Disconnect the air supply before clearing jams or servicing the tool as directed.
5. Price the complete setup
Include compatible staples, a suitable hose and fittings, and the required air supply when comparing air staplers. Check the compressor’s output against the tool’s stated demand. Confirm that replacement fasteners are readily available in the lengths your projects need.
Choose air staplers around the work you actually plan to do, then check the manual before buying accessories. Our air tool and compressor guides explain related equipment choices.
The Amazon listings commonly associated with these two tools do not match what they claim to be: the ASIN often linked for the US58 actually resolves to a meite MT7116 stapler, and the one often linked for the NS150C resolves to a Metabo HPT N3804AB3 — different brands entirely. The correct-model US58 listing on Amazon is also currently out of stock. Both tools are sold directly through Home Depot: PORTER-CABLE US58 and PORTER-CABLE NS150C.
Selecting an air stapler
Air staplers drive staples for upholstery, sheathing and carpentry. Check the staple crown width, gauge and length the tool accepts, and choose staples that match the job.
- Confirm the operating pressure range and your compressor’s capability.
- Sequential trigger modes reduce accidental firing.
- Depth adjustment prevents overdriving.
- Keep the tool oiled if the manufacturer requires it.
Safety
Wear eye protection, keep fingers away from the nose and disconnect air before clearing a jam.
