Stay-Put Threaded-Stud-Mount Folding Pull Handles

Detents keep these handles in the extended or folded position—they won't move until you reposition them. Insert studs into holes in your surface and secure from the backside to open and close a variety of doors and drawers on chests, crates, furniture, machines, and equipment. All of these handles have round grips that allow your hand to pivot in any direction.

303 Stainless Steel—Stainless steel handles have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

Anodized Aluminum—Aluminum handles have mild corrosion resistance, are lightweight, and are nonmagnetic.

Knob-Grip Retractable Spring Plungers

With the most versatile handle we offer, these fit in tight spaces while still giving you something to grab. A tug retracts the nose so you can make controlled adjustments. Use these spring plungers for everything from positioning workpieces to changing the height of tables and platforms.

Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.

Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. Steel is best for dry environments, however, since moisture will cause it to rust.

Twist-to-Lock—Free up both hands to adjust your workpiece or switch out parts without the plunger springing back and getting in the way. Pull back the handle and twist to lock the nose in its retracted position.
