Rubber Feet

Quick Answer: Rubber Feet are small rubber buffers fitted under the base of an instrument, box, stand or piece of apparatus. They keep the item from sliding, protect the bench surface and absorb some vibration.

Small Parts With Three Jobs

Hard bases on hard benches slide, scratch and rattle. A set of rubber buffers raises the item slightly on points that grip the surface, so a power supply stays put when a lead is pulled, a wooden box does not scrape the bench, and a small motor or pump passes less buzz into the table. They also lift the base clear of shallow spills.

Feet are fixed in different ways: some have a screw or bolt through the centre, some have a self-adhesive back, and some push into a hole in the base. Which type this listing supplies, and its diameter and height, should be matched to the item being fitted, since a screw-mounted foot needs a drilled base and an adhesive one needs a clean, flat surface.

Soft mounts are not always an advantage. Analytical balances need a rigid, level support, and a heavy item on very soft feet can rock. For a whole cushioned surface rather than individual points, a rubber pad or rubber laboratory mat may suit better.

Fitting Tips

• Clean and degrease the base before fixing self-adhesive feet, and press them firmly for a few seconds.
• Fit at least three, or one near each corner, so the load is shared and the item sits level.
• Do not overtighten screw-mounted feet, which squashes the rubber and reduces its grip.
• Replace feet that have hardened, cracked or started leaving marks on the bench.

Applications

• Retrofitting power supplies, meters and small instruments that slide on the bench
• Wooden apparatus boxes, stands and demonstration boards
• Small pumps, shakers and motors where vibration should be damped
• Student-built projects and models in STEM and workshop classes

Why Choose LabEquip

Feet are bought by technicians refurbishing apparatus and by schools running STEM and workshop projects. LabEquip lists them in the General Lab Products range; describe the items to be fitted on the contact page.

Frequently Asked Questions

Which fixing type should I choose?

Screw-mounted feet are the most secure for heavy or frequently moved items. Self-adhesive feet suit light items with smooth, flat bases. Push-in types fit bases that already have holes of the right size.

How many feet does an item need?

Three feet always sit without rocking, even on a slightly uneven bench. Four, one near each corner, give more stability for rectangular items on a flat surface.

Will rubber feet stop vibration completely?

No. They reduce the transmission of vibration, particularly higher-frequency buzz, but large or low-frequency vibration needs purpose-made isolation mounts.

Can I put them under an analytical balance?

It is not advisable. Balances need a rigid, level support; soft feet can let the balance tilt or move, which affects readings. Use the balance’s own levelling feet on a stable table.

Why did the feet leave black marks on the bench?

Some rubber compounds transfer marks to pale or plastic surfaces, especially when warm. Non-marking compounds avoid this; clean marks with a mild detergent and consider a different compound.

Do the feet still grip on a wet bench?

They lift the base slightly above shallow spills, which helps keep it dry, but grip is reduced on a wet surface. Wipe the bench dry to restore their hold.
