Wow never saw a track that couldn't be cut?
Who ever this manufacture is just lost a few sales because being able to cut a track is essential to making the product installable in all locations, custom fit is a must for a good looking job, although you have to join tracks together to make a complete system, in most cases it looks much better when you can install a track with out joints, and I have had problems with loosing connection at joints so putting a bunch of tracks together is not my preferred method, as the less joints I feel is a more reliable installation.
most aluminum tracks I just cut with a carbide tip saw, I have used my 18 volt Dewalt to cut many tracks and it provides a nice clean cut as long as you don't try to force the blade, let the saw do the work and go slow, steel track I use my 18 volt Dewalt sawzall or a good hack saw, but again go slow and if no type of clamp table is available just screw the track to a board or exposed wall studs to hold it firm, and make sure you cut square, and also make sure the conductors don't slide out or they will be to short, I always cut the conductors about 1/4" shorter then the length of the track, or if one track end is in, 1/8" more off the other end to allow the other track end or coupler to fit, also try to keep the cut end where a track end blank will go, as if you don't get it square it doesn't show as bad.
Got a brand name to this manufacture? would definitely like to avoid them in the future.
