The 25mm high commercial threshold kit is designed to create a watertight seal between industrial roller shutters or sectional doors and the floor, effectively sealing gaps of up to 25mm. This threshold also acts as a barrier against leaves, dust, and debris, helping to maintain a clean and dry environment. Constructed from durable aluminum extrusion, it can withstand heavy traffic while its low profile allows for easy passage of forklifts and pallet trucks without obstruction. The kit consists of seamless, interlocking sections of aluminum for straightforward installation.
