Replacing the latch or the throw member in a BEST 7KC, 8K, 9K or 6K cylindrical lock? Find the latch by series and backset, narrow or wide face, deadlocking, spring or drive-in, and the throw member BEST lists for each series.

Have an Ilco cylinder number like 7185-SC1-26D-KA2 from the box or an old order? We read it field by field with Ilco's 2026 catalog: mortise lengths and pins, cam codes, rim and 1599 key-in-knob tailpieces, keying codes, and the cylinder length a 4500 deadbolt needs.

Replacing a core or the cylinder of a knob or lever lock with a GMS part? See how GMS numbers its IC6, IC7 and large format cores, which construction cores it lists, and how to read a K001 code such as K001SC26DA2.

Worn Baldwin thumbpiece, a door thicker than the set allows, or a door bored for another lock? We sort the 5399 repair kits, thick door kits, 2-1/8 and 1-1/2 inch adapters and latches by the job, from the Estate and Reserve books.

Replacing a gasket, hammer head nut, hinge or lock case on a CRL Fallbrook glass partition? See how the CRL codes separate Fallbrook from Fallbrook XL parts, which push-in gasket CRL shows for each transom glass thickness and where its documents list each part.

A Kingston Brass clawfoot tub that rocks, a lost bolt, a drain to replace or a faucet for holes already in the tub: what Kingston's pages, spec sheets and instructions say to check for each part, with the VCT3D663019NT8 as the example.

Kingston Brass faucet splashing or running weak, or the aerator lost? Start from the faucet number. Kingston's faucet page can name the aerator, and the aerator's own page gives the exact thread, male or female, and, where printed, the flow of its restrictor.

A Kingston Brass side sprayer that seeps water without being pressed may have a worn spray diverter. Kingston's own lists show which faucet series take KSRP1271D and which take KSRP1241D, and its repair sheets show how each one comes out.

A cracked porcelain button, a worn lever or a missing flange on a Kingston Brass faucet? Before you order, check what Kingston's page for that part gives: the side, the broach, the handle series it lists or the flange size.

Replacing one worn pivot on an ABH offset-hung door? See which set it belongs to, which top, bottom and intermediate pivots ABH pairs with the 0117, 0147, 0195 and 07212 sets, their door weight limits and why the hand matters.
