NGP NGP-176DKB – Frequently Asked Questions
1) What is an overlapping astragal and how does it work?
An overlapping astragal is a vertical sealing member that covers the gap between paired doors. The active door overlaps the inactive door when closed. This design provides superior weather sealing and security compared to split astragals.
2) What doors is the NGP 176DKB compatible with?
This astragal works with paired commercial doors where one door serves as the primary active door. Verify door thickness, edge preparation, and manufacturer specifications before ordering. Check for proper clearance and hinge placement compatibility.
3) Which door gets the overlapping astragal installed?
Install the overlapping astragal on the active door that closes last. This door will overlap the inactive door when fully closed. The inactive door typically requires a coordinanted flush bolt or exit device.
4) What is the dark bronze finish specification?
Dark bronze provides a durable architectural finish suitable for commercial applications. This finish resists corrosion and maintains appearance under normal weather exposure. Verify finish matches other door hardware for consistency.
5) What grade rating does this astragal meet?
Verify grade requirements with local codes and project specifications. Commercial astragals typically meet institutional or heavy duty performance standards. Consult manufacturer documentation for specific grade certifications and test results.
6) Does this astragal meet fire door requirements?
Fire door applications require listed astragals that maintain the door assembly rating. Verify this model appears on the door manufacturer's fire listing. Non-listed astragals cannot be used on fire-rated openings.
7) What additional parts are needed for installation?
Installation typically requires mounting screws, weatherstripping, and coordination with door hardware. Check if strike preparation or additional hardware is needed on the inactive door. Review manufacturer templates for complete part requirements.
8) How do you install an overlapping astragal?
Mount the astragal to the active door stile using manufacturer-provided template. Ensure proper overlap with inactive door when closed. Adjust door coordinator and hardware operation as needed. Follow all manufacturer installation instructions and local codes.
9) How do you maintain and adjust this astragal?
Inspect weatherstripping and mounting hardware periodically. Replace worn seals to maintain weather protection. Check that doors close properly with full overlap. Lubricate moving parts if applicable and tighten mounting screws as needed.
10) What are similar astragal options?
Alternative astragal styles include split astragals and removable mullions. Consider different finishes and manufacturers for matching existing hardware. Browse our door hardware section for compatible options.
11) What field conditions affect astragal performance?
Wind pressure, temperature changes, and building movement can affect sealing performance. Ensure proper door frame alignment and adequate structural support. Consider local weather conditions when specifying weatherstripping materials.
12) How do you measure for astragal replacement?
Measure door height, stile width, and overlap dimension required. Note existing hole patterns and hardware locations. Verify door thickness and edge preparation. Take photos of current installation for reference when ordering replacement parts.
