A small order of my 1063 series line clamps awaiting stainless hardware. Second photo has a 812 series clamp in lower corner for size comparison. These line clamps have interchangeable inserts so you can change line size without changing the whole clamp. You can easily drill the insert to fit any O.D. tube size. 1063 series clamps fit line size 7/16" to 5/8".IMG_2726-1_zpsxb4wonoe.jpgIMG_2725-1_zps5bfxjmxx.jpg
