Drop Down Seals

Drop down seals, also known as guillotine seals or automatic door bottoms, use a plunger mechanism that lowers the seal automatically when the door closes and lifts it when opened. This seals the gap at the bottom of the door for sound, fire, and smoke without dragging on the floor or requiring a raised threshold. Shop our selection of drop down seals, including mortice and surface-mounted options with acoustic performance ratings. With robust aluminium construction and Document E compliance, they provide reliable performance for high-end joiners and commercial installers. Order drop down seals today and benefit from an expansive stock range, trusted brands, and fast next-day delivery.
