I use a number of different products from Gravity and cannot fault the build or finish, as a manufacturer they hit the mark in both of these areas continually, these T-Bars do not disappoint. Overall width of this bar is 1235mm with 6 nut/bolt mounting holes on either side (12 in total on the Bar) spaced at 85mm intervals, 35mm O-Clamps also fit the T-Bar perfectly and could also be used to secure your lighting fixtures. These T-Bars will fit a standard 35mm stand, so you could use a standard speaker Tri-Pod stand or one of the excellent products available from Gravity such as the space saving LS 331 B Lighting Stand. The T-Bar locks into place using a simple locking bar which simply folds across, giving a secure placement which is also very quick to unlock and remove, saving time when setting up or breaking down. Overall a great product with plenty of mounting options both for the Bar itself and how you wish to attach your lighting fixtures. Gets 5 stars from me. Recommended.
