813 × 2032mm Door Jamb — 42 × 140mm Meranti Timber Section
An extra-wide section door jamb for the thickest walls and deep masonry openings, the 813 × 2032mm Meranti door jamb in a 42 × 140mm section is the solution when even a 120mm jamb won’t fully span the wall depth. Common in older double-skin brick construction, extra-thick plaster applications, and insulated wall builds found across South Africa — from Johannesburg’s established suburbs to Cape Town’s heritage properties. Supplied unassembled and untreated for on-site fitting.

Why Choose a 140mm Section Jamb?
Where a 120mm section covers most thick-wall scenarios, the 140mm section is needed for walls where the total depth — including plaster on both faces — exceeds 120mm. This is typical in older double-skin brick homes, walls with thick plaster coats, or builds with added insulation layers. The 140mm section delivers a flush, seamless finish on both faces of the wall. If you’re unsure whether you need 120mm or 140mm, measure the full wall thickness including plaster on both sides before ordering.

Frequently Asked Questions
What size is this door jamb?
The door opening size is 813mm wide × 2032mm high. The outer frame dimensions (wall-to-wall) are 873mm wide × 2065mm high. The timber section is 42 × 140mm.
What is a door jamb and how does it differ from a door frame?
In South African trade usage, a door jamb typically refers to a wider-section frame — usually 100mm or more — used where walls are thicker than a standard frame can accommodate. A standard door frame typically comes in 44–68mm sections. Both serve the same structural purpose: lining the door opening and providing a surface for the door to close against.
What is the difference between the 120mm and 140mm section jamb?
Both jambs are the same door opening size and timber species. The 140mm section is wider, suited to walls where the total depth — including plaster on both faces — exceeds 120mm. Measure your full wall thickness including plaster before choosing between the two.
What timber is this jamb made from?
This door jamb is manufactured from Meranti, a durable hardwood widely used for door frames and jambs in South Africa.
Is this jamb supplied assembled or unassembled?
It is supplied unassembled and untreated — as loose components — for on-site assembly and installation by a carpenter or installer.
