I installed the 48" FastTrack rail with 1 hook for my string trimmer, 1 hook for the powerhead of my pole say, 1 universal hook for the saw section, and 1 sideways bicycle holder. All equipment fits nicely in the hooks (even that polesaw head on the universal) and the bike rack seems very sturdy and well spaced from the wall.
Installation was easy for me and should be for anyone with basic construction skills. I used the hardware pack included with the rail, installing screws directly into my studs on 16" centers and using the supplied anchors between as depicted in the instructions. For extra support I installed more anchors and screws (enough to fill all the top holes and half the bottoms) since I had some hardware leftover from another project.
All you need is a cordless drill, 1/8 bit, 5/32 bit, phillips bit, hammer, tape measure, and a level. The larger bit is for the supplied anchors, the hammer to drive them flush, and the smaller bit for pre-drilling the holes in the studs (makes screw installation much easier). Tape and level are to line it all up.
