NGP NGP-229SSS 36 – Frequently Asked Questions

1) What is the NGP 229SSS automatic door bottom seal used for?
The NGP 229SSS provides automatic sealing at the bottom of doors. The stainless steel construction offers corrosion resistance for commercial applications. The silicone seal creates an effective barrier against air, sound, and moisture.
2) What door thickness does this 36-inch seal fit?
Verify the door thickness compatibility with the manufacturer specifications. Most automatic door bottoms accommodate standard commercial door thicknesses. Check the mounting template to ensure proper fit before installation.
3) How does the automatic mechanism work?
The automatic door bottom activates when the door closes, dropping the seal to contact the threshold. When the door opens, the mechanism retracts the seal. This prevents drag during door operation while maintaining a tight seal when closed.
4) What finish does the stainless steel have?
The NGP 229SSS features stainless steel construction for durability and corrosion resistance. Specific finish details should be verified with manufacturer documentation. Stainless steel provides a professional appearance suitable for commercial applications.
5) Is this suitable for fire-rated doors?
Check with the manufacturer and local authorities for fire rating compatibility. Some automatic door bottoms are approved for fire-rated assemblies. Verify compliance with applicable building codes before installation on fire doors.
6) What tools are needed for installation?
Installation typically requires a drill, appropriate drill bits, screwdrivers, and measuring tools. A router may be needed for mortising depending on the door construction. Follow the manufacturer template for precise positioning and cutting.
7) Can the seal height be adjusted?
Many automatic door bottoms offer adjustment capabilities for proper sealing. Check the product documentation for adjustment procedures. Proper adjustment ensures the seal contacts the threshold without excessive pressure that could cause premature wear.
8) How do I maintain this door seal?
Regular cleaning of the track and mechanism prevents debris buildup. Inspect the silicone seal for wear or damage. Lubricate moving parts as recommended by the manufacturer. Replace worn seals to maintain effective performance.
9) Are replacement parts available?
Replacement seals and mechanisms are typically available for automatic door bottoms. Contact the manufacturer or check our door hardware section for compatible parts and accessories.
10) What threshold works best with this seal?
Smooth, level thresholds provide the best sealing performance. The threshold surface should be clean and free of irregularities. Coordinate with threshold selection to ensure compatible profiles for optimal sealing.
11) How do I measure for the correct size?
Measure the door width accurately. This 36-inch model fits doors of that width. Account for any door edge preparation requirements. The seal should span the full door width for complete coverage.
12) Will this work in high-traffic areas?
The stainless steel construction and automatic operation make this suitable for commercial high-traffic applications. Regular maintenance becomes more critical with heavy use. Monitor seal condition and mechanism operation in demanding environments.
