Thresholds and ramps

• Saddle thresholds (the 400, 500, 600 and 800 number ranges) come in widths from 4 to 10 inches, with heavy-duty HD versions.
• Bumper thresholds have a built-in vinyl, neoprene or silicone seal for exterior doors.
• Thermal break saddles (8425 to 8430) separate the inside and outside of the threshold.
• Interlocking ramps are listed as ADA compliant: R series for heights from 1/2 to 2 inches and RO series for offset transitions.

Seals and door bottoms

Jamb perimeter sets come in vinyl, neoprene and silicone, and the adjustable 103, 107 and 1038 sets are acoustic. The 700ES set works with parallel arm closers. Sweeps come in nylon brush, vinyl and neoprene, and automatic door bottoms include surface and full mortise models. See thresholds and weatherstripping.

Fire door gap solutions

NFPA 80 limits the clearance around a fire door. NGP sells products listed for openings where that clearance is too large: GAP90 for the frame perimeter, HP90-ME for the meeting edge of pairs, 9590 for the bottom and 9990 for the top. 5050 and 2525C self-adhesive fire and smoke seals are listed too.
