HOG has standardised accessories - the stainless steel Wall Kit - as well as standard threaded connectors that can be supplied by HOG retailers or assembled DIY.  See installation videos below.
HOGs use 1" (25mm) diameter brass threads for the top and bottom cast-in connections.
HOGs use galvanised steel Unistrut for the wall kits.
Outlets for HOGs can be either a 1-inch-threaded ball valve or a faucet outlet.  HOGs can connect to a pump, or can be installed vertically and used via gravity pressure to hose or drip-irrigate a landscape.
