Screw Compressor Clamp

Used to regulate flow through a flexible tube. The screw driven jaw can be accurately adjusted in any position from closed to fully open to allow you to get just the rate of flow you want. The swing-away bottom jaw design lets you install over already connected tubing. The jaw opens to a maximum of 7/8" high and is 15/16" wide. Made of nickel plated steel, all edges are rounded to avoid cutting the tubing.

Mylar Warmth

They have the look of something designed for the space program. They're mylar, a paper-thin shiny metallic sheet, that comes in handy when your car breaks down in winter, or when you're separated from your climbing group on the slopes of Mt. McKinley. Barring that, they're also a perfect material for a do-it-yourself cold-climate Halloween costume-near impossible to rip by hand, but cut easily with scissors. There's no padding, so they wouldn't be too comfy on your bed, but they sure are warm. They both come folded about the size of a wallet. The Blanket is 52" x 82", the Sleeping Bag is 34" x 84".

Suit Your Soil

Suit Your Soil

Grow a beautiful garden full of plants that love your soil! It's easy if you know your soil's pH, and we have a gauge to help you! Stick the probe into moist soil for the pH to register in a separate 4" x 2" x 1" gauge box on the end of a 26 ft. cord. That let's you keep the probe in the garden while reading the gauge at your doorstep! A needle indicates the pH on a scale of 3.5-9, and you get a list of which plants like which pH levels.

Affordable, adaptable lab equipment for serious scientists with laughable budgets. The basic stand is heavy black metal 8" long x 5" wide x 1" high with a 19-1/2" x 3/8" dia support rod screwed into it. Position a beaker or bunsen burner on the stand and build the configuration you need above it. Both of the Burette clamps and the ring attach to the rod with thumbscrew clamps. The Burette clamps have wing nuts so they can be adjusted to any angle. The single clamp extends 4" from the rod, with rounded, uncoated, adjustable metal jaws with spring tension and a wing nut.

Not Petri Hobby Dishes

Surpies (regular A.S.&S. fans) know that there is nothing better than a Petri dish for holding small parts for a model, beads for a craft item, or specimens from a field trip, unless it’s something that works like a Petri dish but costs less. We’ve got that!! And they’re so inexpensive you that you can buy enough for those few odd nails, screws, bolts, and tourmalines. These heavy–duty, clear–plastic bead containers are about 3/4” deep. They stack, with the bottom of one dish becoming the lid of the one below it. The 2–3/4” rounds come in a pack of (4) with (4) lids, so they can be used separately.

Peekaboo Canisters

Our aluminum canisters with clear glass pull–off lids are cool. The smallest canisters are aluminum–colored, a set of (20) 1–1/4” dia x 3/4” deep in a 6–1/2” x 5–1/4” x 7/8” lightweight aluminum box with a hinged lid. When the box is shut, a layer of foam padding inside the lid presses down on the canisters, keeping them securely closed. If you need slightly larger canisters, and a cardboard box will work instead of a carrying case, try our colorful display of anodized tins. They are packaged in sets of (12) and come in great assorted colors and are 2” dia x 7/8” deep. Each is an ideal carrying case for paints, many different screws, or other sets of small items or quantities that must remain separate. Prices are per set.

Eat Your Heart Out, Martha

At last, the perfect gift for your brother-in-law who has everything. Fill our brand-new, individually wrapped, empty toothpaste-type tubes with your own homemade treat: guava toothpaste with pumice, pigeon-liver pate, free-flowing fudge. The aluminum tubes are 1-1/2" dia x 7-1/2" long OA, open at one end (waiting to be crimped shut), and with a nozzle and screwcap on the other end. They have lithographed labels. The tubes are being stored in the warehouse, of course, so you're going to want to be judicious about putting real food in them....

Water, Water Everywhere

The Noah's Flood Alarm alerts you instantly to a leaking hot-water heater or an overflowing tub. Place the small, flat plastic sensor where water shouldn't be. A 10-ft white wire leads to a 3-3/8" x 1-3/4" x 3/4" plastic housing with an LED alarm and (2) "AA" batteries (yours, not ours). When the sensor gets wet, the LED will flash and a buzzer (think alarm clock) will sound and save the day.

ALL Things To ALL People

This deluxe ABS storage case is called a Store-It-ALL, and it does. But it could be called a Carry-It-ALL, for the sturdy handle and locking clasp, or it could be called a See-It-ALL, for its translucent lid. Or a Fits-It-ALL, for the removable dividers that let you configure it with any number of compartments from 5 to 26. But the 12" x 18" x 3" OA case should really be called ALL-I-Ever-Needed- To-Get-Organized!
