Question: does this kit come pre assembled or do i need to assemble it on site?
Document: I did some research, and the Johnson pocket door hardware seemed to be highly regarded. I installed it carefully, and it is the smoothest operating pocket door I've ever used. I did spend some extra effort to be sure that the track was installed level and had absolutely no bow to it. I did replace the trolleys with the &#34;heavy duty&#34; trolleys. I don't need the extra load capacity, but these operate even smoother than the standard trolleys that come with the hardware kit.
Nice kit. Go to the Johnson site and check out their install videos. Makes it a piece of cake for new installers. Kit is well put together. I have installed two of these units.
I needed a pocket door for my kids' bathroom remodel, and I really thought I'd have to call someone else to install one. I've never installed any type of door before so this made me nervous. No need - the kit came with everything I needed to install it (once my rough opening was ready for it) and very clear instructions. I haven't actually hung the door yet, but getting the track and pocket installed was a breeze.
My first pocket door installation went relatively smooth with this kit. When it comes down to it you are paying for the rollers and these are easily twice as good as the &#34;pre-hung&#34; pocket doors I saw at HD and Lowes. The hardware is stronger and the rollers are smoother.Installation took about an hour not including drywall (from a rough opening).
Track and rollers are very good quality and the finished door rolls very smoothly. My project was a success, but I wish I would have known before starting that I was going to need 3/4&#34; drywall... I wasted time there and had to swap it out on the whole wall to have it all match.
Spend the money on this version. Well constructed. Buy the kit for the wider door sizes just in case you settle on a quality exterior slab door for your pocket door.
It works good, Sliders work really nice, like all pocket door tracks the studding that comes with the kit is thin but the metal support is good and thick.
Basically i gave 4 stars to this kit for the following reasons: the provided studs wood with steel covering are very good idea but because of the size and such they FLEX - very easily...and there is only 2 sets of them.
This is a very well thought out kit. It is very easy to install and very strong. A huge improvement over the old pocket doors. I bought my kit from a local store for 59.00 and a slab door for 40.00
Needs adapter kit for 1 3/4&#34; doors inspite of works with either 1 3/8&#34; or 1 3/4&#34; doors. Be nice to know that before it is delivered and needing to be installed.
Answer: yes
