Works Great
I was a little hesitant after reading some of the reviews about how it doesn't center very well and needs modifications. I have had zero issues with it. I have put up 800 sq ft of siding for a separate garage, and I have had no issues with it. I am very glad I purchased because it has saved me a TON of time compared to nailing by hand.

Works good despite reviews
Works great despite bad reviews. I put a regulator on the gun for depth control. Definitely necessary. But the regulator/tip combo saves a lot of time and sweat

Needed modificaton, but fine after that
I understand a lot of the negative comments as I found this adapter to be poorly shaped for siding. The idea was right, but the size and depth / shape of the device makes for far too many missed shots. I had a conversation with it and my die grinder and was able to get it to be very reliable. I did remove a fair amount of material to get a nice step that fit nicely around the siding locking rib, but there is still plenty of material left, and it does not seem to have compromised its structure at all. I tested on some scrap siding by nailing it to some scrap wood until I had it right. Pretty much only missed when I got sloppy after that . With a better notch to fit the siding, all i had to do was place the guide peg in the nail slot of the siding and make sure I held the gun fairly straight. If you are not prepared to modify this adapter and do some practice shots you may not be happy with the results. I have done a lot of construction, but I am not a pro at siding, so this was way faster for me compared to using a hammer. One plus was while on a ladder I could nail with one hand, and do it as far away as I could possibly reach. As I can only get better at using this, I feel I would stay with using it. I gave it 4 stars simply because it can be made to work well, as opposed to no other adapter option out there for the dewalt roofing gun that I already owned.

Quick shipping
Just vinyl sided over an asbestos sided house, ordered $200 adapter else where, perhaps order didnโt process? So I quickly ordered this for my new Bostich, and it came quickly! This is a nosing replacement and had to use some force to exchange it. After the first day I took my grinder with me to remove metal from it to hug the siding better. Still a little finicky, this siding was cheap and thin and unhemmed on top of nail slot, it broke thu at times in 70-80 degree weather (Nail connecting barbs perhaps). I didnโt adjust air pressure, setting 2 on gun worked well. Also installed gun hook. Still learning it, with hemmed edge siding maybe 7/8 success rate? Also used magnetic air palm nailer for tight spots and some channels, worked well.

Great product
I wish I wouldโve bought these along time ago. They make the job easier and a better quality than not using it and they save time and when youโre in business, saving time is I wish I wouldโve bought these along time ago.

Spend the additional money and buy a Reed EZ Nailer!
This product does not work. It does not center the nail in the slot. I destroyed so much siding trying to learn this attachment. I ended up returning this product and went with a REED Ez nailer attachment. Well worth the extra money to be able to have to ease of putting up siding with a roofing nailer.

Meh.
This was a wasted purchase IMHO. For any vinyl trim pieces you can't get the gun square enough for a true shot into the nail slot. When nailing actual siding there seemed to be no rhyme or reason nailing. The nail would center punch the slot, punch the slot, nail thru the siding, punch the slot, nail thru the siding. Ended up just nailing it all by hand. Should have paid attention to reviews elsewhere saying same.

Works with modifications
Worked well but profile is not universal. I needed to grind down a portion of the adapter in order for the nails to line up properly centered, otherwise great option for installing vinyl siding.

She works
It actually works, as long as the head is aligned properly and the nailer is flush to the wall. It does double nail hear and there, but that's because the roofing nailer isn't made to press the trigger for each nail. I found that it works well at 80psi. At the end, if you do siding as a career, your better off buying a stapler, much easier and you can use it for your corners and J channels ect. But if your like me and already have a roofing nailer and just need to do siding once, then it's worth it as apposed to spending much more on a stapler.

The New toy.
I have done siding by hand for years. This tip makes the job go so much easier after you learn how to use it and the angle to shoot the nailer.

Well worth the price
Been using this adapter for about a year now and I absolutely love it. I have my own siding company, so I install tons of vinyl. It's super easy to change out with the existing roofing attachment on the Bostitch nailer. It comes with an extra spring as well and fits the Bostitch roofing nailer perfectly! This attachment was a game changer for installation speed! Would definitely buy again.

Could be better
Got the siding tip from siding tip.ca for dewalt nailer and these at same time these are no where near as nice

Good product
If you don't set the adapter e3xactly in between the vynil hooks it will not work, but 5 stars anyways as makes the job way faster.
