KILARGO IS4030 75MM HEAVY DUTY THRESHOLD PLATE 11MM H
KILARGO IS4030 75MM HEAVY DUTY THRESHOLD PLATE 11MM H
The Kilargo IS4030 is a heavy-duty anodised aluminium threshold plate (75 mm wide, 11 mm high), used with Kilargo door bottom seals to help prevent rain infiltration, draughts and smoke penetration at the doorway. Supplied with PVC bedding feet to eliminate vibration, noise and moisture ingress beneath the plate.
Key Features
What It's Used For
Fit the IS4030 at external and internal doorways in commercial and residential buildings where a robust threshold must bridge floor junctions and give the door bottom seal a flat landing – entries, balconies, corridors and plant rooms.
Combine with a Kilargo automatic bottom seal or sweep seal to complete the weather, draught and smoke barrier at the door bottom.

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.
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 IS4030 come in?
Standard lengths are 1000mm and 2250mm, and it can be ordered in 250mm increments from 1000mm to 3250mm. 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.
