Dewalt Guide Rail Square Kit


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 Dewalt 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.

    NOT TOO HARD TO INSTALL...
    This CCV kit seems adequate. People say that because the hoses supplied with these kits are more brittle than the genuine BMW parts, these are tough to install... But they're really not. The ends on these hoses SWIVEL and you can sort of eyeball which way you need the fitting to be pointing BEFORE you put them on your manifold... They swivel, but they're tight and it takes a little force to turn them. ALSO, a little dab of silicone gel or a spray of silicone out of the can, into the fittings on these makes a world of difference when clicking them on... For the price, I highly recommend the kit.

    Great value
    I recently had to replace the starter on my 2001 325i E46 with about 150k miles. While I had the intake off, I figured it would be a good time to replace the CCV because I was unsure if it had ever been done. My old CCV literally fell apart as I removed it, so I'm glad I replaced it. The new parts were a little tough to put together, but overall came together well enough. A lot can be forgiven for the price. I would recommend assembling the system before installing in your vehicle to get a good sense of how it all goes together and to hopefully loosen up the fittings just a tad before installation. 50skid on youtube has a great DIY for doing this job. I only finished this job yesterday, but my car has been running great. I can't yet confirm, but this may have solved my running lean problem.

    Cheap plastic parts -- good fit
    They are what they are: Cheap plastic parts. They fit, but long-term durability will be a challenge. Probably will buy from FCP Euro going forward (and just did for a fuel line replacement).

    Does not connect
    First the hoses do not connect together causing all kinds of vacuum leaks. There is no rifling in the diaphragm so oil leaks back up. Cheap piece of plastic
