Sliding Door Handles & Locks

Sliding door handles & locks — OEM replacements, in stock

If your sliding door handle is loose, snapped, or pulling out of the door,
you’re in the right place. Slide Master Hardware stocks genuine OEM
sliding door handles, lock bodies and matching keepers for every major
Australian aluminium door brand made over the last 30 years — Jason, Dowell, Stegbar, Bradnams, Boral, Comalco, Trimview, Vantage and Trend.
Real parts, real fit, fast Perth dispatch Australia-wide.

Replacing a broken sliding door handle?

Most sliding door handle failures fall into one of four categories:

Internal cam or spring failure — the handle still moves
but no longer drives the lock bolt. Fix: replace the lock body, not the
external handle.
Cracked or snapped handle face — usually UV-degraded
plastic on doors 15+ years old. Fix: replace the external handle pair
(inside + outside) so the screw alignment matches.
Worn keeper / barrel — handle works fine but won’t lock
shut. Fix: replace the keeper plate and check the door alignment hasn’t
dropped onto the bottom roller (a slumping door pulls the keeper out of
reach).
Broken sliding door latch — the latch arm or spring inside
the lock body has failed, so the door won’t catch shut even when the
handle moves freely. Common on older Stegbar,
Trimview and Comalco
units where the latch and lock body are separate parts. Fix: replace the
latch mechanism — sometimes a standalone part, sometimes the whole lock body.

If you can’t tell which one applies, browse by brand below — most product
pages include the original OEM part code so you can match against the
moulding stamp on your existing handle.

Sliding door handles by brand

Jason
Windows — handles for the Boltlock series, Affinity range, and
the older Jason commercial sliding door hardware. We carry both the
internal hook lock assemblies and external pulls.

Dowell
— full range of Dowell sliding door handles, including the
DS970-style D-handle & lock units for Dowell sliding doors built
from the early 2000s onward, plus the matching keepers and strikers.

Stegbar —
Stegbar replacement sliding door handles and lock bodies for both the
Aneeta-era and post-merger Stegbar units. Phase out parts and current parts
side-by-side.

Bradnams
— Bradnams sliding door handles and keepers for residential aluminium
sliding doors. Older Bradnams units share componentry with several
WA-builder house brands; if your handle isn’t stamped, send a photo.

Boral — Boral
windows and sliding door handles, locks and lock spare parts. Many Boral
parts are interchangeable with Dowell and Trend equivalents from the same
era.

Comalco —
Comalco sliding door handles and matching cylinders for the older
aluminium-framed glass sliding doors common in 1980s-1990s WA homes.

Trimview —
Trimview sliding door handles, locks and keepers. Common in 1990s-2000s
WA project-home aluminium doors; we stock matching cams, spindles and
external pulls. Send a photo if your handle isn’t stamped — Trimview
parts share a lot of DNA with several house-brand units.

Sliding door handle & lock compatibility

Most aluminium sliding door handles are handed — left-hand or
right-hand — based on which way the door slides shut. The handed-ness
matters because the cam inside the handle has to throw the bolt toward the
fixed jamb. Buy the wrong hand and the lock simply won’t engage. The brand
pages above show handed variants where it matters.

Two more compatibility checks before you order:

Spindle length — measure the square steel rod that
connects the inside and outside handles. Standard Australian sliding
door spindles are 8 mm square, but length varies (typically 60–95 mm).
Screw centres — the vertical distance between the two
mounting screws. The most common centres on AU sliding doors are
85 mm and 90 mm; wrong centres mean redrilling the door stile.

Sliding door latches, locks and snibs — what’s the difference?

The terms latch, lock and snib get used
interchangeably, but on Australian aluminium sliding doors they’re three
distinct mechanisms — and knowing which one has failed saves you from
buying the wrong replacement part.

Sliding door latch — the spring-loaded arm that catches
the door shut when you push it closed. On screen-side sliders and lighter
security doors the latch is often a standalone part you can swap without
touching the main handle. On heavier patio sliders the latch arm lives
inside the lock body, so the whole lock body comes out as one unit.
Sliding door lock — the keyed barrel and bolt that
secures the door against forced entry. On most modern AU sliding doors the
lock and latch share one housing; on older Trimview,
Stegbar and Wunderlich units they’re often two
separate parts, which means you can replace the failed half without
changing the working half.
Sliding door snib — the small thumb-turn or slide bolt
on the inside that engages the lock without a key. Worn snibs are the
most common "the door won’t lock" complaint we see, and the cheapest
fix on the page.

If your sliding door latches shut but won’t lock, you
usually need a new lock body or keeper, not a new handle. If it doesn’t
latch at all, the spring inside the latch has gone — replace the latch
unit. Window latches follow the same logic: the
Trimview window latch and
Wunderlich sliding window latch are the two we get asked for most often,
and both share parts with the matching sliding-door units from the same era.

How to identify your sliding door handle

Don’t guess — three steps narrow it down quickly:

Check the door for a brand sticker on the inside top
rail, the strike plate, or the bottom corner. Most aluminium doors
built after 1995 are stamped or stickered.
Photograph the existing handle from the inside,
outside, and edge-on. Old part codes are often moulded into the back of
the external face.
Measure the screw centres and spindle as above.

out of our Wangara WA showroom — odds are we’ve seen yours.
