Pemko 434ARL 30 – Frequently Asked Questions

1) What is the Pemko 434 full mortise automatic door bottom used for?
The Pemko 434 provides automatic sealing at the door bottom when the door closes. It mortises into the door bottom edge to create a weatherproof seal against thresholds. Commonly used on exterior doors and fire-rated assemblies.
2) What door thickness does the Pemko 434 fit?
Verify door thickness compatibility with manufacturer specifications. Most Pemko 434 units fit standard commercial door thicknesses. Check the mortise depth requirements against your door construction before ordering.
3) Does this door bottom require specific handing?
The Pemko 434 typically installs universally without hand-specific orientation. The automatic drop mechanism activates based on door position regardless of swing direction. Confirm installation requirements with the manufacturer template.
4) What finish options are available for the Pemko 434?
Pemko door bottoms come in various finishes including mill aluminum, dark bronze, and other architectural finishes. The specific finish for this 36-inch length unit should be confirmed at time of order to match your door hardware.
5) What is the duty rating for the Pemko 434?
Pemko 434 automatic door bottoms are designed for commercial duty applications. They meet requirements for high-frequency use in institutional and commercial buildings. Check project specifications for specific performance standards required.
6) Does this door bottom meet fire code requirements?
Many Pemko door bottoms are listed for use in fire-rated assemblies. Verify the specific fire rating and listing information for code compliance. Installation must follow manufacturer instructions to maintain fire rating integrity.
7) What replacement parts are available for the Pemko 434?
Pemko offers replacement seals, springs, and actuating mechanisms for their automatic door bottoms. Contact the manufacturer or browse door hardware sections for compatible replacement components.
8) How is the Pemko 434 installed in the door?
Installation requires mortising the door bottom edge to the specified depth and width. Use the manufacturer template for precise positioning. The unit fastens with through-bolts or screws depending on door construction. Professional installation recommended.
9) How do you adjust the Pemko 434 after installation?
The drop mechanism includes adjustment screws to control seal extension and retraction timing. Adjust the actuating pin position to ensure proper seal contact with the threshold. Follow manufacturer instructions for fine-tuning performance.
10) Are there similar Pemko models to the 434?
Pemko offers various automatic door bottom models including surface-mounted and concealed versions. The 434 series includes different lengths and configurations. Browse Pemko products for related weathersealing solutions.
11) What field conditions affect door bottom performance?
Extreme temperatures can affect seal flexibility and mechanism operation. Heavy debris or damage to the actuating pin impacts proper function. Regular cleaning of the threshold area prevents interference with seal operation.
12) What are the key measurements needed for installation?
Measure door width, thickness, and bottom rail height. Verify threshold height and gap requirements. The 36-inch length fits doors up to that width. Confirm mortise dimensions and fastener locations using the installation template.
