Pemko 142A 36 – Frequently Asked Questions

1) What is the Pemko 142 series interlocking threshold used for?
The Pemko 142 series is designed for residential applications where water protection is critical. The interlocking design creates a tight seal with door bottoms while the water return feature directs moisture away from the interior.
2) What door types are compatible with this threshold?
This threshold works with residential entry doors that use compatible door bottom seals or weatherstripping. Verify your door bottom hardware matches the interlocking profile before ordering.
3) How do I determine the correct width for my door opening?
Measure the door frame opening width precisely. The threshold should span the full opening width. Common residential widths are available in 4-foot lengths that can be trimmed to fit.
4) What finish options are available for the 142 series?
Pemko typically offers mill finish aluminum and anodized finishes. Check the specific product listing for available finish options that match your door hardware.
5) What is the load capacity of this threshold?
This residential-grade threshold is designed for normal foot traffic loads. For heavy-duty applications or commercial use, verify load requirements with manufacturer specifications.
6) Does this threshold meet building code requirements?
The 5/8-inch height is designed to meet most residential codes for accessibility. Always verify local building code requirements for threshold height limits in your jurisdiction.
7) What accessories are needed for installation?
You may need end caps, sealant, and fasteners depending on your installation. Check if compatible door bottom weatherstripping is required for proper interlocking function.
8) How is this threshold installed?
Installation typically requires removing old threshold, preparing the opening, and securing with appropriate fasteners. Use sealant around edges to prevent water infiltration. Follow manufacturer installation template.
9) How do I maintain the water return feature?
Keep the water return channels clear of debris and leaves. Periodically check that water flows away from the interior and that interlocking seals remain tight.
10) What other Pemko threshold models are similar?
Consider other Pemko threshold options like the 143 series or flat thresholds if interlocking function is not required for your application.
11) Can this threshold handle different floor heights?
The 5/8-inch height accommodates typical floor transitions. For significant height differences, you may need shims or a different threshold profile to achieve proper drainage.
