Magnetic Seal Tip for Sliding Doors

For most 180° sliding shower doors, the standard gap is around 22mm.

As a simple guide:

Your actual gap should be equal to or smaller than the seal’s rated gap.

👉 This helps ensure the magnetic strips meet properly and close securely.

(i.e., Your gap ≤ Seal's rated gap)
