Effortless Installation Guide

Follow these quick steps for a professional-grade weather seal:

1. Measurement: Measure the width of your door. If necessary, trim the Lineshading Door Sweep to length using a hacksaw or heavy-duty shears.
2. Positioning: Slide the U-shaped channel onto the bottom of the open door, ensuring the fin slightly compresses against the threshold when the door closes.
3. Marking: Align the pre-drilled holes. On metal doors, mark the spots and pre-drill small pilot holes if required.
4. Securing: Use the included white-headed screws to firmly bolt the sweep to the lower face of the door.
5. Testing: Swing the door open and closed to ensure smooth operation and complete floor contact without binding.

Why Choose Lineshading?

Flimsy stick-on silicone strips quickly peel away due to dirt and foot traffic. Lineshading provides a mechanical, screw-secured PVC solution that locks directly onto the door frame. By combining a rigid slide-on body with ultra-flexible bottom fins, this kit stands up to thousands of door cycles. It is the smartest, longest-lasting upgrade to weatherproof both front and back entryways simultaneously.
