A door leaf is heavy, flat and finished on both faces, and it is carried by its edges. The four corners take the knocks, the long edges take the strap, and the bottom edge takes the floor. A bendable U protector covers both faces and the edge in one part, and turns the corner without a joint at the point that gets hit first.
Where door leaves get damaged
Corners first: a leaf stood on end lands on one corner, and a painted or veneered corner cannot be repaired invisibly.
Then the long edges, where a band crosses the finished face and prints through. Then the bottom edge, where the leaf meets the floor when it is stood up.
A bendable length along each long edge, notched at both ends, covers all three of those in two parts per leaf.
Specification at a glance
Doors are 35-55 mm thick, which is a wide channel compared with a panel. The leg stays short, because the faces are finished and the protector only has to hold and protect the edge.
| Leaf | Inside width | Leg | Wall |
|---|
| Hollow core 35 mm | 36 mm | 40 mm | 3 mm |
| Solid core 44 mm | 45 mm | 40-50 mm | 3-4 mm |
| Exterior 55 mm | 56 mm | 50 mm | 4 mm |
| Fire rated 54 mm | 55 mm | 40-50 mm | 3-4 mm |
| Bottom corner in a rack | As leaf | 40 mm | Doubled |
Interior, exterior and fire-rated leaves
Interior hollow-core leaves are light and the risk is corner crushing. Exterior and solid leaves are heavy and the risk is the edge taking the weight when stood up.
Where a leaf carries a certification, the pack is usually specified too, and the protector must come off without leaving adhesive or a mark. Paper, no tape, no staples.
Fire-rated leaves are packed the same way; the protector plays no part in the rating and should never be described as doing so.
Standing, stacking and the strap
Doors are usually stood in a rack or stacked on edge. In a rack, the bottom corner takes the whole weight and needs a heavier wall or a doubled piece at that one point.
Where a strap crosses the leaf, the channel spreads it. Keep the leg longer than the strap is wide, so the strap lands on board rather than on the edge of the protector.
Questions buyers ask before ordering
How many parts per leaf?
Two lengths, one per long edge, each notched at both ends. Plus corner pieces where the leaf sits on a rack.
Will the protector mark a painted door?
A clean dry board does not. Grit between board and paint does, so keep the bundles wrapped.
Is it suitable for fire-rated leaves?
The pack is; the protector plays no part in the rating and we do not describe it as doing so.
What wall for a door stood on end?
4 mm, or a doubled piece at the bottom corner which carries the weight.
Does it leave adhesive?
No adhesive is used anywhere on the pack.
