Measurement help
Measure the clear opening — the actual gap water would pass through — not the door leaf. Measure in three places and use the smallest. Full step-by-step in the measuring guide.
Before you buy, confirm
- The threshold and frame are sound and even.
- The opening is within the product's supported range.
- You understand this reduces — not guarantees — water ingress.
Estimate only. Prices shown are PLACEHOLDER values pending Sean's confirmed price book and manufacturer datasheets. Final suitability depends on your opening, and no temporary barrier can guarantee protection in every flood.
