Automatic Door Bottoms (Drop Seals)
Surface, Semi-Mortice and Full Mortice
Drop seals of all types are designed to close a uniform size gap. Our drop seals can seal up to19mm gaps, provided the gap is consistent. Gaps that start at less than19mm and then grow cannot be closed. The drop seal utilizes a straight aluminum extrusion so it cannot close an inconsistent gap.
