01 — The opening
The measurement that matters is at your header
Not a size picked from a range. Header depth, mounting surface, post width and material, the slab edge and whether power can reach the opening all decide what is possible — and they are site facts, not catalogue facts. It is why we measure before quoting and why a number produced from photographs should be treated with suspicion.
- Every opening is measured and specified individually.
- Two openings on one patio can need different answers.
- We do not quote before we measure.
