Our each is a set of (4) removable sink strainers with stainless steel mesh wells and flat rims. The set includes (1) 4-1/2" dia for 2-1/4" drains, (1) 2-3/4" dia for 1-1/8" drains, and (2) 2" dia for 3/4" drains.

These are the split rings with the beveled profile, the good ones. The bevel and the largeness of these rings translate to fewer chipped fingernails and blurted-out obscenities. Measure 1-1/2" dia x 1/8" thick, in steel, and hold a bunch of keys.

Wallace’s pooches before Gromit came along? Nope, just a handy 2-3/8" long x 3/8” ID steel snap hook attached to a 13/16” ID ring that swivels 360 degrees. In some fashion circles, hanging your keys from a belt loop of your jeans with one of these is considered mandatory.

The solution to spare keys, and attaching any number of things to any number of other things, is the ubiquitous split ring. These are the even ubiquitouser 15/16" OD x 1/8" steel ones. And at this price you could buy enough to string together to make a steel curtain and add a little snazz to your pad.

This float valve assembly has a 2-15/16" x 1-9/16" dia white, barrel-shaped plastic float on a 1" x 1-1/4" stainless steel arm, making it look like a float valve for a Lilliputian toilet tank. Arm is connected to a 1/4" ID check valve with a 1" long flattened shaft and cotter pin connector. Designed for a bottom mount.

Black plastic vented grilles with (19) round holes measure 2-1/8" OD x 3/8" thick with (4) snap clips to hold them in place. Originally for stereo speakers, they were designed to fit into a 2" dia port.

No, O-rings. Get ’em here, because we got ’em. These black rubber (neoprene, we believe) O-rings are nominally 1-1/2” ID and 1/8” thick, and made in the USA. Use them for crafts, tiny ring toss games, in dioramas or dollhouses, as vibration pads, or in actual O-ring applications. Because, after all, they’re O-rings.

O my. It's time to restock the O-ring cabinet. You'll get (36) total, (6) bags of (6) black rubber O-rings, all 1/8" thick. Each bag will have (2) 1-3/4" OD x 1-1/4" ID and (4) 3/4"OD x 1/2" ID. Made in the USA.

Hardware from Monkey Grip, Inc.? Those would be professional–quality tire repair products –– in this case, air–line couplers with a 1/4 NPT thread on one end and a fitting for a T–type connector on the other. The 1–1/2” long interchangeable steel nipples have T–connectors that are threaded. Excellent quality, whatever your application.

What do you give a plumber for his birthday? We recommend some longer T-shirts and maybe some of these 3/8” white PVC 90-degree elbow fittings. Fittings are 3/8” ID and a tad over 1” long on both legs; they come with mating nuts and gaskets.
