L-Track section and heavy duty stud fasteners

Levi helps me demonstrate how 2 position heavy-duty studs fit into standard L-track.

L-track, airline track, or "Logistics Track" is a standard for rigging and securing loads for transport. The tracks/rails are installed permanently in vehicle floors, walls, or ceilings. A variety of fittings are available which provide for threaded studs to screw things to (what we cover here), as well as single, double, and triple "rings" to place hooks through. A common application is to use ring fittings and ratcheting straps to tightly secure an arbitrarily shaped load in minutes. It does not seem to be commonly used on buses, except for securing wheel chairs.

There are a variety of different fitting types that can lock into L-track, and a fitting can be installed in any position, in 1-inch increments. The tracks/rails are a single piece of aluminum and weigh almost nothing, owing to their airline heritage. L-Track is a standardized component and you can find it from a few online dealers, in various surface profiles. It is/was cross listed as military standard MS-33601

Since I don't need quick reconfiguration, L-track is probably overkill for my main application, which is securing the in-motion vehicle seats in my Skoolie conversion. However, the use of L-track lets me choose a desired seating position independently of where it is most convenient to drill through the bus floor. It also lets me fine-tune the seat pitch depending on what kind of trip we'll be taking and which passengers will be aboard. Assuming symmetrical seat benches, it lets me swap benches from passenger to driver side, and it would let me setup a bench as rear-facing if I wanted to have a dinette or other arrangement.

Finally, if I feel like taking some of the seats out and securing thousands of pounds of cargo with ratchet straps (as long as the cargo fits through a school bus door), this will work for that also :)

Correction: In the video, I remark that the track-mounting holes are on 4 inch centers, but I'm mistaken -- they are clearly 5" OC. You can get L-track with or without pre-drilled holes. The holes for mounting the tracks to the host vehicle are not covered by the standard, and in actual aircraft installations, the holes are typically setup for 100-degree angle screws instead of the 82 degree screw heads you commonly find. This L-track, and most of the easily available stuff, is pre-drilled for normal 82 degree flat head screws; any normal 1/4" flat-head screw at your local hardware store will be fine.
