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.

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.

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.

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.

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.

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.

Get your keys organized before everything uses iris recognition. Choose between a set of nickel-plated steel split rings at 3/4", 1", 1-1/4" and 1-1/2" dia, or a set of (4) rubber key caps/covers in red, yellow, green and blue. Karen, our Boreal Studies Professor, says they look like tiny little stocking caps on her keys, and she should know. (Our pkg 2 gets you 8 covers)

The world of surplus works in mysterious ways. Here we have assorted V-shaped aluminum channels 5-3/4" long x 5/8" wide across the 120° Vs. Picture these nestled behind glass thermometer tubes, imprinted with assorted scales, each with a small mounting hole at the top, maybe tiny crimp-clips to mount the thermometer that isn't there, and a diamond-shaped opening at the bottom for the glass bulb that also isn't there. Then add your own thermometers, use them as teaching aids, string 'em together for tracks or marble runs, or get really creative.

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.
