Pemko 151A Flat Smooth Saddle Threshold - 3" x 1/4"
The Pemko 151A is a professional-grade Flat Smooth Saddle Threshold designed for maximum accessibility and durability. Measuring 3 inches wide and a low-profile 1/4 inch tall, this threshold is engineered to provide a barrier-free transition that is fully ADA compliant. Manufactured from high-quality mill aluminum, the 151A is the ideal solution for interior or exterior doorways that require smooth wheelchair access while maintaining a fire-rated safety barrier.
High-Performance Features
- ADA Barrier-Free Design: The 1/4" height eliminates tripping hazards and provides an effortless transition for wheelchairs, carts, and hospital beds.
- Fire-Rated Safety: Rigorously tested and UL10C Positive Pressure certified, making it suitable for use in fire-rated openings where life-safety compliance is mandatory.
- Superior Sealing Surface: The flat, smooth top is specifically designed to pair with Automatic Door Bottoms [link], creating a perfect, level sealing point to prevent drafts, moisture, and sound infiltration.
- Architectural Compliance: Meets ANSI/BHMA A156.21 standards for thresholds and A117.1 for accessible and usable buildings and facilities.
- Energy Efficient: Helps maintain interior climate control by minimizing air leakage under the door, contributing to lower utility costs and LEED-certified building requirements.
