Frequently Asked Questions
What does “kit form” mean — does it arrive assembled?
No. The KFB4/NS is supplied unassembled in kit form. This is intentional — shipping an unassembled frame significantly reduces the risk of transit damage. The kit is pre-drilled and pre-dipped, making on-site assembly straightforward. Screws, adhesives, and braces are not included.
What is included in the kit?
The kit includes the pre-drilled and pre-dipped timber frame components with factory-fitted composite rubber gaskets. Screws, adhesives, and braces are not included and must be sourced separately.
Is this frame suitable for a double door?
Yes. The KFB4/NS is specifically designed for double door configurations, with a 1612mm opening width and an 86mm x 42mm section profile suited to wider entryways.
Does this frame come with a sill?
No. The KFB4/NS is a sill-less (NS) model, making it ideal for interior doorways or sheltered exterior entrances where a sill is not required. If you need a frame with a sill, browse our range of Swartland Winsters frames with sill options.
What timber is used in this frame?
The KFB4/NS is constructed from solid laminated and finger-jointed wood, engineered to resist warping and twisting over time for long-term dimensional stability.
What does “pre-dipped” mean?
Pre-dipping is a factory-applied timber preservative treatment that protects the wood against rot, fungal decay, and insect attack. It is not a primer or paint — the frame will still need to be primed and painted after installation.
What are the rubber gaskets for?
The composite rubber gaskets are factory-fitted to the frame and provide a draft-proof seal when the door is closed, improving insulation and reducing air infiltration around the door.
What guarantee does this frame carry?
The KFB4/NS is backed by Swartland's 5-year guarantee, covering manufacturing defects and material quality.
