Installation Instructions

Tools Required:

• Hacksaw (if cutting to length)
• Measuring tape
• Marker
• Rubber mallet (optional, for secure seating)

Step-by-Step Guide:

1. Measure: Measure the length of your existing sill threshold to determine the required length for the extender.
2. Cut (if necessary): If the extender needs to be shortened, use a hacksaw to carefully cut it to the desired length. Ensure a clean, straight cut.
3. Align: Position the M-D Building Products 67106 extender over the existing grooves of your compatible M-D sill threshold.
4. Snap into Place: Gently press down along the length of the extender to snap it securely into the grooves of the existing threshold. A rubber mallet can be used to lightly tap it into place for a firm fit, if needed.
5. Verify: Ensure the extender is fully seated and flush with the existing threshold, providing a continuous surface.

Usage and Functionality

Once installed, the threshold extender provides an increased surface area for your door sill, improving the seal and offering enhanced protection against external elements. It helps to prevent drafts, moisture, dust, and insects from entering your home, contributing to a more comfortable and energy-efficient environment.

Maintenance

• Cleaning: Regularly clean the aluminum extender with a mild soap and water solution. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
• Inspection: Periodically inspect the extender for any signs of wear, damage, or loosening. Ensure it remains securely snapped into the existing threshold.
• Sealing: If desired, the ends of the extender can be sealed with appropriate caulk or sealant to further enhance weather protection.

Troubleshooting

• Extender not snapping securely: Ensure the existing threshold is compatible with the M-D Building Products 67106 extender. Check for any debris in the grooves that might prevent a proper fit. Apply even pressure or use a rubber mallet for a firm snap.
• Gaps after installation: Verify that the extender is fully seated along its entire length. If gaps persist, consider applying a weather-resistant sealant along the edges for improved insulation.
