Cavity Slider Hardware

Cavity slider hardware covers the mechanical and functional components that make a sliding pocket door operate — flush pulls, privacy locks, rollers, guides, and soft-close mechanisms. This collection brings together the hardware you need whether you are fitting out a new cavity frame or replacing worn parts on an existing door.

What types of cavity slider hardware are there?

The main hardware categories are flush pulls, privacy locks, roller assemblies, bottom guides, and spanners. Flush pulls sit recessed into the door face so nothing protrudes when the door slides into the wall. Privacy locks add a turn-and-release function for bathrooms and ensuites. Rollers and guides keep the door tracking smoothly, while a spanner tool is used to adjust or tighten the roller carriage inside the cavity frame.

Which flush pull suits a cavity slider?

A flush pull designed specifically for cavity sliders sits completely flush with the door surface, typically recessed 4-6 mm into a routed pocket. Standard rectangular flush pulls suit most door thicknesses from 35 mm to 45 mm. Round or square variants are available to match contemporary hardware finishes. For a cleaner look on painted or timber doors, a flush jamb pull is morticed into the door edge rather than the face, removing the visible recess entirely.

Finish options across the range include satin stainless, matte black, brushed nickel, and brushed brass. Matching your flush pull finish to other door hardware in the same room keeps the overall scheme consistent. For handles across cabinetry and internal doors, see the cabinet handles and interior door handles collections.

How do cavity slider privacy locks work?

A cavity slider privacy lock uses a turn-knob or coin-slot mechanism on one side of the door that engages a bolt into the door frame, preventing the door from sliding open. From the outside, an emergency release slot allows entry with a flat-head screwdriver or coin. Most Australian-market privacy locks suit doors from 35 mm to 45 mm thick and require a hole diameter of 52 mm or 54 mm. They are sold separately from flush pulls, so you can combine the two components from matching ranges.

What opening sizes do cavity sliders come in?

Standard cavity slider frame sizes in Australia are 620 mm, 720 mm, 820 mm, and 920 mm, referring to the rough opening width in the wall frame. The actual door leaf is approximately 10-15 mm narrower than the frame size. For an 820 mm frame the rough opening in the wall is typically 1670 mm wide (to allow the door to disappear fully into the cavity on one side) and 2040 mm or 2340 mm high. Hardware components such as rollers and guides are generally sized to suit standard frame kits, so confirm the frame brand before ordering replacement parts.

When should you use a soft-close cavity slider?

Soft-close mechanisms use a damper integrated into the roller carriage to decelerate the door in the last 100-150 mm of travel, preventing it from slamming against the stop. They are worth specifying in high-traffic areas, children's rooms, and anywhere noise between rooms matters. Soft-close roller sets are a direct replacement for standard rollers in most Hume, Corinthian, and EzyJamb cavity frame kits. Check the frame brand's compatibility guide before purchasing, as roller track profiles vary between manufacturers.

What are cavity slider rollers and guides, and when do they need replacing?

Rollers are the wheeled carriages that hang the door from the top track inside the cavity frame. Guides are the small floor-mounted or jamb-mounted brackets that prevent the bottom of the door from swinging out of plane. Rollers typically last 10-15 years under normal use, but nylon wheel wear, bent tracks, or debris in the cavity can cause the door to drop, stick, or veer. Replacement rollers are sold in pairs and must match the track profile of your frame kit. Guides are sold individually and are usually stainless steel or nylon.

What should you check before buying cavity slider hardware?

Confirm the door leaf thickness (most commonly 35 mm or 40 mm), the frame brand (Hume, Corinthian, EzyJamb, Triline, or similar), and the rough opening size before ordering. Flush pulls and locks have minimum door thickness requirements that are listed in product specifications. If you are replacing components rather than fitting new hardware, photograph the existing roller carriage and track profile — this makes it significantly easier to match the replacement part. For broader bathroom hardware pairings, the mirrors and shaving cabinets collections are worth browsing alongside cavity slider hardware for ensuite fitouts.
