A closed-loop or D-shaped pull set back from the leading edge, letting the door be drawn shut without the hand passing behind the closing edge. Reaching around the edge to a flush pull is what makes a cubicle door difficult from a seated position.

Length helps more than diameter. A long vertical pull gives a choice of grip heights, which suits both a standing user and someone reaching up or across from a chair.

Accessible cubicles frequently carry a second, longer pull on the inside face for this reason, and it is positioned by the swing of the door rather than centred on the leaf.

A knob does. Turning or gripping a round knob needs the hand to close and apply torque or friction, which is hard for arthritic hands, wet hands and hands carrying something.

A pull only needs the hand hooked behind it, and a loop can be operated with a forearm or a closed fist. That is why guidance on accessible washrooms steers toward pulls and away from knobs.

Cubicle doors rarely have latching handles at all, since the latch is separate, so the handle is doing only one job and there is little reason to choose the shape that does it worst.

Because the door is used in both directions. The outer face pull is for opening an empty cubicle, and the inner face pull is for drawing it closed behind you, which is the movement that is awkward without one.

Back-to-back fitting also solves a fixing problem. A through-bolted pair sandwiches the door leaf, so the load is carried between two plates rather than by screws biting into a laminate core.

Where only one face is fitted, it is normally the inside, because the outside of a free cubicle door can be pushed rather than pulled.

Through-bolting is the durable answer. The two escutcheons clamp the door between them on a machine screw, so cycling loads are taken in compression through the panel rather than in shear on a thread cut into laminate.

Where only one face is fitted, the fixing relies on the panel core, and a threaded insert or a barrel nut spreads the load far better than a woodscrew into compact laminate.

Thread-locking compound or a nylon-patch screw stops the slow loosening that comes from thousands of small pulls, which is the usual reason a handle starts to rotate on its fixing.

Continuous surfaces and a gap large enough to get a cloth behind. A pull standing clear of the door on solid posts can be wiped all round; one with a decorative collar or a knurled grip traps residue in the pattern.

Finish plays a part. A satin or brushed surface hides marks between cleans but holds slightly more residue in the grain than a polished one, which shows every fingerprint and cleans completely.

Antimicrobial coatings are offered, though they supplement cleaning rather than replace it. Geometry that lets a cloth reach every face does more for hygiene than a coating on a shape that cannot be wiped.

No, and treating them as interchangeable is a mistake. A cubicle door pull is sized to move a light leaf and is fixed into a partition panel; a grab bar is rated to take a substantial proportion of a person's body weight and is fixed into structure.

A door is a moving element on hinges. Anything that invites a user to bear weight on it is transferring load into hinges and a pilaster never designed for it.

Where support is needed near the door, it belongs on a fixed wall or pilaster as a rated grab bar, with the door pull kept clearly to its own function.

The positions differ more than the parts. An outward-opening door needs the inside pull placed so the user can reach it without stepping back into the swing, which usually means closer to the hinge side than instinct suggests.

Outward-opening doors are common in accessible cubicles precisely so a collapsed occupant does not block the leaf, and that layout changes where a comfortable grip falls.

The hardware itself is generally the same. What changes is the setting out, and it is worth marking the positions with the door hung rather than working from a standard dimension.
