Planet Automatic Door Bottom Seals

Planet by ASSA ABLOY is the world's leading manufacturer of automatic drop-down door seals, made in Switzerland since 1945. Planet seals close the gap between door and floor when the door is shut, providing sound insulation, smoke containment, fire resistance, and energy efficiency without the need for a threshold.

Planet US Automatic Door Bottom
The core drop-down seal for swing doors, double-leaf doors, and folding walls. Profile width of just 8 mm. Sound insulation up to 48 dB. Standard lengths from 335 mm to 1585 mm, with extra lengths available up to 6000 mm. Smoke-tight and fire-retardant depending on version.

Automatic Door Bottom (9/16" and 3/16")
Width-specific variants for different door and groove profiles.

Planet Pivot Module
Add-on trigger mechanism for rebated pivot doors. Uses a rotating activator that eliminates lateral forces on the seal, reducing operating force and extending service life. Requires only a 16 mm hole in the sealing groove, no additional frame machining. Available in black and stainless steel.

Planet Pivot Ramp
Optional accessory for the pivot module that minimizes the seal's grinding distance, further reducing the force required to open and close the door. Available in black and stainless steel.

Planet SN Sliding Door Bottom
Drop-down seal designed for sliding doors. Seals without reset force or locking mechanism.

• Interior swing doors (single and double-leaf)
• Rebated pivot doors (standard and oversized)
• Sliding doors
• Folding walls
