Need a custom size loop? Start by counting how many drive links your bar requires. Enter that number in the box above, then add to cart. Be sure to double-check your count before ordering. Custom Chain Loops are NOT eligible for returns - they are final sale. However, if you've miscounted the number of links you need, contact us for assistance. The price shown above is a "per driver" price. Not sure how to identify what chain you need? Follow this simple guide to understand all the complexities. EXAMPLE Using this chain as an example: Oregon 72CJ (3/8" X .050) Square Chisel Full Skip Chain 72 → Series number C → Cutter style J → Grind style 3/8" Pitch → The spacing between the drive links (the “teeth” that ride in the bar groove) .050 Gauge → Gauge is the thickness of the drive link (the part that fits in your bar’s groove).
