Levelling feet · Cup base

A cup pivot foot is moulded as a shallow cup rather than a flat pad. The end of the profile leg seats inside that cup, so the cup both locates the leg and spreads its load over a larger area than the profile section alone would.

Two benefits come from the shape. The bearing footprint on the floor is wider than the profile end, which lowers the pressure on the floor and makes the frame harder to tip. And the profile end is enclosed by the cup wall, so the raw cut face and the section are hidden — useful on a frame whose legs are visible at eye level, or on a frame that has to present a clean, closed appearance at floor level.

The cup does three things a flat pad cannot

Locates the leg The cup wall captures the profile end, so the leg cannot slide across the pad while the foot is being adjusted. On a frame being assembled that removes a step: the foot stays where it is put.
Spreads the load The bearing diameter is the outside of the cup, not the profile section. A 40 mm profile in an 80 mm cup doubles the bearing diameter and cuts the floor pressure to about a quarter.
Conceals the end The cup wall covers the cut face of the profile. On a display or retail frame, or on any frame where the leg ends at floor level and is visible, that removes the need for a separate end cap.

Where the cup shape helps most

Visible legs at floor levelA frame whose legs are seen from the side gets a closed, moulded foot instead of an open profile end sitting on a disc.

Frames on a soft or coated floorThe wider bearing area lowers the floor pressure, which matters on a screed, a raised deck or a coated finish where a point load would mark or spall.

Frames that are re-positionedThe cup locates the leg, so the foot stays aligned with the profile when the frame is lifted and set down again.

Frames assembled on siteThe leg drops into the cup and stays there while the frame is levelled, which makes a one-person assembly practical.

Practical point: a cup foot replaces the end cap as well as the levelling foot. If the leg already has an end cap specified, tell us — with a cup foot the cap is not needed and comes off the bill of materials.

Joint, stem and the floor

The joint is normally a ball or a shallow pivot so the cup can sit flat on an uneven floor; without it, a wide cup on an angled leg contacts on one edge and loses the bearing benefit the shape was chosen for. The stem is a standard M8 to M16 thread that screws into a thread insert in the profile end, and the cup is usually supplied in PA6 nylon for the same floor-protection reasons as any other nylon-based foot.

Where the frame is heavy or the floor is rough, a metal cup is available. It is heavier and more expensive, but it will not deform under a point load and it survives a floor that would cut into a polymer base.

Frequently asked questions

Does the cup fit any 40 mm profile?

It fits any profile whose outside section is 40 × 40 mm. The cup is moulded to the outside dimension, so a profile with a different wall thickness still fits, as long as the outside is the same.

Do I still need an end cap?

No. The cup wall encloses the profile end, so the cap is not needed on a leg that ends in a cup foot.

Will the cup hold water?

A cup foot is a shallow dish, so on an outdoor or wash-down frame specify the drained version, which has a small relief in the cup floor so water does not stand in it.

Is a cup foot more stable than a flat pad?

Yes, on the same floor. The wider bearing diameter raises the tipping resistance and lowers the floor pressure, which is why it is used on frames with a high centre of gravity.

Can the cup be supplied in metal?

Yes, for heavy frames and rough floors, in zinc-plated or stainless steel.
