GoKeyless is a trained and authorized Lockey® dealer. Sales, service, and support. It's why thousands of clients around the world choose GoKeyless™ for their security and access control needs each year. Best New Gate Product for 2013 Way more secure than having to manually close your gates!  As seen at FenceTech 2013, the new TB450 adjustable closer is a hit among gate installers, contractors, and retail gate customers.  An upgrade to the extremely high selling TB400, and TB400SS, the new TB450 makes installation and use even easier by allowing you to simply adjust the speed at which your gate closes instead of needing to pull out and re-mount the post bracket. Compared to higher cost gate closers offering only one closing speed, and which can be a mechanical nightmare when installing, the TB450 has less moving parts, is made from steel, comes with premium grade fittings for reliability, and lets you adjust the closing speed, saving you time and effort when you put it in.
