Kadee 807 On3 Plastic Couplers w/Gearboxes Brown Centerset 2 Pair

The Kadee 807 is an On3 Scale coupler set finished in brown (boxcar red), supplied complete with plastic couplers, matching plastic gearboxes and lids, and the mounting hardware needed for a straightforward drop-in installation. Each 807 coupler carries a 9/32" centerset shank, measured from the back of the head to the center hole of the draft gearbox, and pairs with the #846 On3 Scale centering spring and #847 On3 Scale knuckle spring for reliable magnetic knuckle operation. This industry-standard design mounts cleanly in place of the earlier #803 couplers and works with S Scale draft gearboxes.

Every package holds two complete pairs, giving you four couplers and four gearboxes with lids in brown, plus six #846 centering springs, two extra #847 knuckle springs, and 0-48 x 3/8" mounting screws. The plastic draft gearboxes measure 37/64"L x 3/8"W x 11/64"H, and Kadee lists a 5/8" mounting height with a 9/16" centerline and 1/16" trip pin height. For setup and tuning, the 807 pairs well with the #813 On3 coupler height gauge. Made in the U.S.A.
