Biothane Fi Holder will safely and securely attach your Fi receiver onto any collar, harness, leash, or other strap. NEW - 2-color versions! Click here. Measure your strap! The width of your strap determines the size of the Fi Holder you'll need. Smaller holders may not fit on wider straps. Larger Fi Holders will fit on narrower straps, however they may be more prone to drooping or twisting - NOT RECOMMENDED for 3/8" or 1/2" straps. You'll need approximately 5" of strap length for your Fi Holder to fit. Measure the space between hardware to ensure there is enough space on your collar/harness. Biothane is waterproof and cleans up with just soap and water. Closures are Chicago screws - install in just a minute with only a flat screwdriver (not included). Works on all Fi Series 3 modules.
