Overview
Powernail makes the 445LSW as an air-driven nailer for hardwood flooring that shoots L-shaped cleat nails. The tool rests on the board edge while compressed air drives each fastener, so installers can blind nail board after board along a room.
Floor installers get a dedicated tool for nailing tongue-and-groove hardwood, which is a different job from trim or framing work. The limits are the thin listing and a model field that does not match the title, so check the exact variant before ordering.
Who it's for
Flooring contractors and serious renovators who nail down hardwood plank across a whole room get the most from a purpose-built cleat nailer. A casual user covering one small area, or someone expecting a battery tool, should look elsewhere.
Pros and cons
- Purpose-built for hardwood flooring work
- Pneumatic drive needs no battery
- L-cleat style for flooring boards
- Moderate weight for a floor tool
- Nail length range not listed
- Requires an air compressor and hose
- Model field conflicts with the title
Performance notes
Air pressure from the compressor drives each cleat nail, so output depends on a steady supply and the regulator setting. The L-cleat fastener is a flooring nail, which holds the board without surface holes in the usual blind-nailing method. Weight matters over a full floor, because the tool is lifted and repositioned for every board.

Frequently asked questions
How do I look after the Powernail 445LSW?
The listing gives no care or oiling steps, so follow the maker's manual for air tool lubrication and cleaning. It confirms only that the nailer is pneumatic and weighs 15.8 pounds.
Why does the model field say 445FLEXPRW?
The title names the 445LSW but the model field in the listing reads 445FLEXPRW. Confirm which version you are buying with the seller before ordering.
Does the Powernail 445LSW work without a compressor?
No. The listing calls it a pneumatic tool, so it needs a compressed air supply to drive nails.
Can I use the 445LSW for stapling or trim?
The listing describes a 16 gauge L-cleat nailer for hardwood flooring and gives no other uses, so treat it as a flooring tool, not a general nailer.
