Porta-Nail 421P Pneumatic Floor Nailer with Both Line Nailer Shoe and Face Nailer Shoe

I bought this nailer based on a culmination of many reviews read from many websites. Additionally, this appears to be the only nailer that has the ability to shoe and face nail. My bother installed wood floors for ten years and he said Porta-Nail is one of the best nailers out there. I haven't used 421P yet, but I am impressed with the build quality. The plastic case leaves a lot to be desired, and for the price of this product and for the quality and reputation of the product I would think that Porta-Nail would include a case with a steel pin hinge instead of the highly susceptible to breakage molded hinge. Just a suggestion Porta-Nail, and you may contact me if you wish to send me a new and improved case to replace this semi-crappy tool holder.

I do general carpentry and finish work. I have used the Porta-Nail 421P to install 14 floors (approx. 300 sq.ft. each).The majority of the floors were 3/4" oak, four were 3/4" Brazilian Cherry. I have had three jams caused by hitting nails in the sub-floor.
The nailer is light-weight for its' size--a bonus.
A lite tap does the job.
Its' easy to clear a jam.
Follow the instructions on setting up your compressor,probably the main cause of problems.
This tool is expensive, but I feel that its' worth the cost.

As a professional carpenter I've probably run over 10,000 feet of flooring with this nailer without a major problem or rebuild. Even works great on harder woods like Ipe. One thing you absolutely have to have is a good compressor (4 cfm or better) and a 3/8" air line. I tried running mine off my smaller pancake compressor with a 1/4" line and it gave me nothing but problems. It continually jammed and didn't set the nails flush. I switched to my bigger compressor and a bigger line and haven't had a problem since. I also prefer the serrated nails to staples as I think they hold better and split the tongue less. I still prefer my old manual porta-nailer for those stubbern warped boards.

This hardwood flooring nailer ,i think, the best of the market,but be carefull- if a loader have less then 1/3 capacity of nails- it start jamming nails.So dont forget reload nails.I think problem is-too weak spring loader mechanism.Anyway, this nailer wery accurate-not damage a tonque of hardwood planks,unlike staplers hardwood nailers.

This is the best flooring nailer on the market. Certainly, it is not a home owner tool, Awesome product with robust performance at each and every use.
Users claims nail jamming, they are simply using an after market nail in this professional grade tool. By the way i am a License utility Mechanical contractor for over 20 years.
I have used many other flooring nailers and fastening systems. If you're seeking an industral grade tool with performance and robustness with every use....May i suggest looking no further.
Personally, we purchase HILTI tools and accessories for our shop....You get the message.
