LockeyUSA Gate Hardware includes chain link gate hardware, gate boxes, gate closers, gate locks, panic hardware for gates, and pool gate hardware. Sumo Gate Hardware started as the GL2 Surface Mount Gate Lock, and now it includes many other features such as heavy duty and self closing gate hinges, single and double sided gravity gate latches, top pull style perimeter gate latches, and the PGL-50 (pool gate latch). In addition to having many types of gate hardware options, Sumo is easy to adjust and install, and it is surface mounted. Another great thing about this hardware is that the steel gate closers come with step-by-step instructions to make installation easy, and they are available individually or by the carton. Not to mention, Lockey offers the very popular GB2500 Gate Box for installing your Lockey locks as well. The GB2500 comes in steel or aluminum.
