    Firm, Quiet Hydraulic Action for Easy Closing of Pedestrian Gates Marry the TB400 to your gate and you'll never see it slam shut again.  Replicating many of the design and functionality features of the Kant Slam gate closer, the Turtle Back does it one better with improved seals and a higher performing cylinder.  With a pre-set closing speed delivering 8 seconds of controlled close, the TB400 Turtle Back automatic gate closer has emerged onto the market as an economical and reliable device to secure pedestrian gate arrangements up to 64" in width (72" if gate is light-duty), and 175lbs.  Hotel pool gates, parking lot access gates, beach access gates, office complex gates, resort gates, and barrier gates, highlight a few of the many places this gate closer can come in handy.  We also recommend the TB400 automatic gate closer for gates which lock by maglock or electric strike because of its steady and stable closing action.  Instead of having to peek around the corner, look out a window, or make a quick run to the gate to ensure it has remained closed, the TB 400 does it for you, letting you focus uninterrupted on what you were doing. Many of our clients use the TB400 in conjunction with the Lockey double sided 2835DC2210DC2830DC1150DC keyless gate locks, and Combi-Bolt CB2000. This powerful hardware combination provides secured, self-closing access control with the convenience of keyless entry.
