PLANET MF Drop-down Threshold Seal 585mm 50dB Trim-to-Size for PVC/Aluminum Doors

Product Overview

The PLANET MF Drop-down Threshold Seal (L=585 mm) is a specialized sealing bar featuring a silicone drop seal, engineered for use on PVC and aluminum profile doors. Designed for environments requiring enhanced noise reduction and smoke control, it achieves a sound attenuation performance up to 50 dB. The 16 mm drop ensures a tight seal at the threshold, supporting installations in commercial and residential settings with demanding environmental requirements.

A key benefit of this model is its trim-ability: the bar can be cut by up to 125 mm, providing flexibility during installation and reducing the risk of mismatched or surplus inventory for installers and facility managers. This adaptability ensures it is particularly suitable for bulk procurement projects involving variable door widths, such as hotel renovations, office blocks, or large residential complexes.
