Since the company refuses to answer questions on RUclips, I had to figure it out on my own. It took me a bunch of searching and driving around but I found what I needed at harbor freight tools. It’s the warrior set of slot cutter bits. The 1/4” bit got me to the depth I needed for my application but still not to 13/16”. There’s a kowood set on Amazon that might also work.
@@VanD3rp did you manage to find adequate router bits online? I am located in Canada and I swear it's impossible to find on that has sufficient depth. Local retailers that are supposed to have cavity sliders equipment do not have it either. It's a bit frustrating.
Why is the depth of frame 3-5/8 rather than the 3-1/2" for 2 x 4 walls? We will need to shim the entire wall in order for drywall to be flat. Is there an explanation for this?
I need this door as a security door inside an office with key card access to open from one side and automatically open on the other side. I believe I can accomplish this with my current maglock security system. My doors are 36" wide and 101" tall. Am I able to use my existing doors and are there framing systems large enough for this door size?

Why W*2+2"? I have ROW of 72"... Can I make that work? (My closing side is already flush with perpendicular wall, and back jam is abutting 2x4 inlaid into exterior wall...) I don't have any more space and want to keep a 36" door... I can replace back 2x4 with 1x4 though to make it 72¾" ROW
For a ROW of 72", the maximum width of your door would be 35". To keep your current door you could cut an inch off the back of the door (where it isn't visible) to make it fit in the pocket.

Mario Zapata. I bought 3 ' kitset pocket frame" and after I assembly the first pocket I noted the (2) split jamb aren't straight. The I opened the second kitset and the both split jamb aren't straight. I called Cavity Sliders and they want me sent pictures by email. I hope they replace the split jam (3 kitset) ASAP. Please check very well all the pieces in the package before
Hi Mario! The outward bowing is normal for our pocket frames, it's been designed that way to compromise for the pressure created during drywall installation. Once drywall and trims are added, the split jambs do straighten up.
Is it possible to set this up with a double cavity and a larger door? So you can slide it into a cavity on both sides when locking to make it more secure?
I have 3 different sized doors to install; 28”, 30” and 32”. The formula that are supposed to guide the extrusion cuts required, make absolutely no sense to me. But that’s probably just me. Are there any further detailed instructions out there? Otherwise, good video.

Basically you're selling a track. The rollers and soft close are made by others and can be purchased separately at a significantly lower cost. The rest can be built on site with structural lumber.
Hi OIC, Site building a pocket frame for a 3 1/2" stud with any structural integrity is tough. We manufacture our rollers and soft close assembly in house. Feel free to give us a call to discuss on 888 466 0030 as it's always good to chat through opposing viewpoints.
Great video! Are there any modifications needed if my door rough opening is a 2x6 wall? Do I need to support the drywall with anything so it doesn't cave in if someone leans too hard or bumps into the wall? Thank you!
For a 2x6 wall, you will need to furr out the frame to ensure there is no deviation in the wall linings from the stud to our pocket frame. To better explain what I mean, check out our Wilshire Curson project, where the builder did just that! ruclips.net/video/Vi-SHnnShso/видео.html If you have further questions, please give us a call at (888) 466 0030 so we can help troubleshoot this with you. :)

Can I attach shelving to the wall where the pocket door frame will be? If so, what length should the screws be so that they don't interfere with the door?
Our Cavity Slider Pocket Frames come with horizontal slats that can be installed at any desired height so you can anchor a cabinet to keep it from falling. If you want to hang small shelves, we recommend adding a substrate like a sheet of plywood behind your drywall. Our slats are 5/8” so your screw length will depend upon your drywall and substrate thickness, plus the thickness of the slats.
Hi there! To remove the door, you'll just need to remove the header trim (via the trim clips) and, using the adjusting wrench, push the small tab on the door's carriage mount plates to release the door.
