Snap-on Saddles are an easy way to add sprinklers to a new or exsisting irrigation system. There is no need to cut pipes and add T fittings. Prime and glue both the saddle and area where the sprinkler head is needed. Snap on the saddle and drill a 1/4" hole through 1/2" female threaded center and into pipe. The thread can be used to add sprinkler heads or adaptors for more 1/2" pipe. Snap-on saddles are available in 1/2", 3/4", 1", 1 1/4" and 1 1/2".
