Kreg Guide Rail Square Kit (for Adaptive Cutting System)


Feature Overview

We worked with engineer Jeff Wagner to bring his rail square idea to market. The goal of this rail square adapter was to be an affordable option that will still produce accurate 90/45 degree alignment.

This is designed to work with Kreg ACS Guide Rails.

Our guide rail square uses the accuracy of the 90/45 degree sides on the aluminum rafter squares to achieve a true 90 and 45 degree angle. We are able to keep the costs down by using a 3D printed cam lock mechanism to secure the square against the rail. There are a total of 4 cam locks, 2 on each side so that you can use the square on either side of the guide rail.

  • The guide rail square creates accurate 90 and 45 degree alignment
  • The guide rail square can be used on either end of the guide rail
  • Strong cam locking system to ensure snug fit to rail
  • Optional Support Tab to keep the rail square flush to your workpiece

Accurate Alignment

Our guide rail square adapter uses the accuracy of an Empire square and the guide rail to achieve accurate 90 degree and 45 degree alignment. The kit installs onto an Empire square within a few minutes. It uses a cam lock system to press the Empire square to the guide rail t-track, achieving a true 90 degree.

90° and 45° Alignment

The guide rail square adapter can be flipped around and used on both sides. This means that you can set up a 90 degree cut or 45 degree on the close side of your workpiece. You can also install the guide rail square on the far side of the guide rail on the opposite side of the work piece.

Optional Support Tab

The Empire square is 12" long, which means towards the end there will be minimal sagging due to the weight. This is common on all guide rail squares. We provide an optional support tab which will let the guide rail square and guide rail sit flush onto the workpiece.

    Overpriced for a cheaply made shirt. The hems are glued down, not sewn.
    Color: Grey/Black Square, Size: XX-Large, Color: Grey/Black Square, Size: XX-Large
    I'm not sure how well this shirt is going to hold up, but I'll give them it's lightweight and cool! LOL There's almost nothing to it, it's so light. Mrs Aloha Friday is really crafty, but doesn't do much sewing. It's like she made this shirt with those tapes that you use to hold a hem temporarily, with an iron. LOL She's now got the idea she can make me shirts herself by just gluing them together! ;o) Neither of us is sure how well this will hold up to multiple washes. I'll edit my review if it falls apart. I think the price is nuts for what you get, at $27 as of this writing. There are literally holes in the shirt! I'd feel better recommending it at around $10. If you need something lightweight, yet still an actual shirt, here ya go. The problem is, I'll need to wear an undershirt under this or I'll just sweat right through it in the heat, and it will show the texture of everything it rests against, like the hairs on my chest. Or worse, they'll poke through the holes! Gah!! LOL So sorry for that imagery. I got the Grey/Black square.

    Esabel.C Mens Mesh Polo Shirt Moisture Wicking Short Sleeve
    Color: Lightblue Rhombus, Size: Large
    This is the Esabel.C Mens Golf Polo Shirt. It's moisture wicking works out great. I wear it quite often golfing. Very comfortable and light weight. The color I got was the Lightblue Rhombus. They have 6 different ones to choose from. And the price is not bad either. As far as the size goes, I went by their chart, which was large, and it fits very well. I've had no problems with it. Like I said, I wear it very often.

    One of my favorite golf shirts
    Color: Lightblue Four Dots, Size: Large
    I ordered this golf shirt and it's becoming one of my favorites. I'm a medium build 6'3", 42" chest and the large fits me very well with plenty of room for movement but a nice trim look. The lightweight material is soft and breathable, with a small bit of stretch. It's easy to care for with machine wash and dry, and comes out wrinkle-free. This shirt is very well made and is a good value - I highly recommend it.
