I'd like to use the space under my front porch for storage. The porch will have a lattice that goes from under the deck to just above the ground, and I want to make a section of the lattice slide like a closet door.
The sliding panel will be a 4' x 2' 2x4 frame holding the lattice, so it won't be very heavy. There will be a similar panel fixed in place next to it, that the sliding panel slides over. For esthetic reasons I want a very small clearance between the top of the sliding panel and the joist it hangs from, so I didn't want to use a standard roller hanger.
I was thinking of using aluminum T-track set into a dado in the joist, and "T-bar" fastened to the top of the sliding panel. To keep the sliding panel from swinging, I'd have another T-track on the inside face of the bottom of the 2x4 frame, and a traveller on the fixed panel.
The top T-track will be two 4' lengths, and I figure I'll file the ends of the T-bar so that it doesn't hang up when it crosses from one to the other.
I'm just wondering whether T-track will slide easily with that much weight over a four foot length. My gut says "sure it will", but I thought I'd ask for a second opinion.
