Customer Questions & Answers

Is this tool for .175 spline that screentight recommends

If so, which screen to you recommend. I am rescreening a screened in porch. My main concern is bugs and mosquito's.
Asked by: Anonymous
This roller knife should do all spline sizes. I did a .140 with it so you should have no problem with the .175.

Is the roller/disc at business end of tool, made of metal?

I am looking for a metal screen spline roller because I've had a bad experience with a plastic one, that I bought elsewhere, having its' roller basically disintegrate.
Asked by: Deloppoled
Roller Head is hard plastic with a groove. Keep an eye on the screw as you use it.

I don't know what size my spline is. I installed it years ago and I've forgotten.

I took it out of the old screen, and have ordered two screens for my balcony doors. But don't know the size of the spline. Please help. I plan to pick up my screens and spline roller on Friday from your Snapfinger Woods store, and pay for it then.
Asked by: tortoise35
If it's fiberglass screen it's probably .140 spline. If it's aluminum screen you want to use .125 spline because the metal is thicker.

Professional Screening Roller Knife is rated 3.9 out of 5 by 14.
Rated 1 out of 5 by from Nice thought... terrible execution I live in SWFL which means I have a screened in pool deck. 3 panels blew out so I set out to replace them. New screen... check. New spline... check. Screen roller... hmm which 1 to get. I skip over the $3.00 cheap roller because I found this amazing roller that comes with a knife and 3 rollers for different kinds of spline. The cutting tool is an added bonus. The roller is worthless. The blade snapped while pulling the old spine out. OK fine, a utility knife and a pair of needle nose pliers step in. The roller itself now becomes the bane of my existence. First you need to pop out the bearing wheel insert and reinsert it into the proper disk. This turns out to be a nasty task and takes longer than installing the screen. Then once all that happens, it doesn't spin freely to install the spline. After wrestling with this thing. What do I do? Borrow a friend's cheap roller that costs about $3.00. Don't waste your time on the clever tool. It's not worth it. Just get a simple roller and call it a day.

Rated 4 out of 5 by from Good for .175 spline but not for the smaller gauge spline, IMO I used this on .140 spline and I went back to my other cheapie spline tool that had a more narrow wheel because I could hear the fiberglass screen being cut occasionally. It seems that if the width of the wheel is bigger than the channel when you push the spline in it can cut the screen. I checked all the screens I used this tool on and I couldn't see any tears along the spline so maybe it just made that crackle sound by hitting the screen but didn't actually cut it. Nevertheless, my cheapie tool didn't ever make that sound so I'm sticking with it. This is made for the thicker .175 spline and is probably perfect for that but I would be reticent to use it with the smaller gauge spline. It's a pretty solid tool so I'm taking away one star for not mentioning it was for .175 spline and giving it 4 stars.

Rated 5 out of 5 by from Better than the standard This spline roller and cutting knife are really nice. I paid approximately five dollars more for it than the other one. I am very glad I did. I was replacing the cheap screens with pet resistant screens since my 70lb puppy can't seemed to keep his paws off of the screening when birds and squirrels are in residence. That screening is exceptionally thick compared to the other. To compound matters my screen cannot be laid flat for the installation it must be installed vertically. This roller was ergonomic enough to get a good grip and really put my back into it. The wheel has a snug fit so no wobbling or bouncing out of the groove. The blade did very well on the cheap stuff but a word of advice, if you're going with a thick pet resistant screen just spring for the husky or stanley box cutter style blade and decrease your spline diameter a little. This blade is razor sharp for standard but not good enough for the tough stuff.

Rated 5 out of 5 by from Works well Good for 0.140 and above spline. Great grip and leverage. Easy to use and works well. Seems durable. I don't use the blade at all, preferring instead a utility knife with a blunt tip blade.

Rated 5 out of 5 by from Worked well I bought this along with the Screen Tight 1.5" track and used it with a fiberglass screen and .175" diameter spline. Using the tool I was able to install the screen by myself, the cutting tool on the end was very useful.

Rated 1 out of 5 by from Ridiculous After a struggle and getting nowhere, I lifted one side of the screen I was attempting to install and tried to put the roller in the track without screen fighting me... and the roller didn't fit! If you're installing a .140 or larger spline, this tool might work, but it absolutely cannot work with a track that requires a very common .125 spline. You would think they might mention that on the package... but they don't. This one will be returned tomorrow.
