Compliance & What It Means
Fire and smoke approvals apply to tested, proprietary door assemblies. Always confirm suitability for your specific door type and required rating with your fire door manufacturer or building certifier.
Is the IS4130 wheelchair friendly / disability compliant?
Yes - its low profile keeps the threshold within the limits of AS 1428.1 (Design for Access and Mobility) and BCA/NCC clauses D2.15 & D3.3, so it can be used on accessible paths of travel without creating a barrier for wheelchairs or a trip hazard.
Does a threshold plate seal the door by itself?
A threshold plate provides the hard, flat (or ramped) sealing surface at the floor - it works together with a Kilargo door bottom seal (automatic drop seal or sweep seal) that closes onto it. The plate stops water tracking under the sill and gives the seal a consistent surface, and the pair together block rain, draughts, smoke and noise.
How is the threshold plate fixed down?
Stainless steel fixing screws and plugs are supplied. Alternatively, most Kilargo thresholds can be bedded in builder's adhesive for a concealed fixing. PVC bedding pads (where supplied) go underneath to eliminate vibration, noise and moisture ingress beneath the plate.
What lengths does the IS4130 come in?
Standard lengths are 1000mm and 2250mm, and it can be ordered in 250mm increments from 1000mm to 5000mm. Plates can also be cut down on site for an exact doorway fit.
What is the handling time for this item?
This is a non-stocked, specialty architectural item ordered directly from the Kilargo factory. Allow a standard handling time of 5–8 business days after cleared payment before dispatch.

I'm not sure this is the right seal for my door — can I get help?
Yes. Door sealing depends on your door type, the gap sizes and what you need to seal against (fire, smoke, sound, weather or drafts). Call Prime Hardware on 1800 329 028 with your door details and gap measurements and we'll confirm the right Kilargo seal, size and finish before you order.
