FAQs
Q: What is the purpose of this equivalency chart?
A: This chart allows you to seamlessly cross-reference figure numbers from a standard hanger catalog to find the exact PTP functional equivalents for legacy Grinnell pipe supports.
Q: Are PTP equivalents structurally identical to Grinnell pipe hangers?
A: Yes. PTP manufactures its equivalents to meet or exceed the load ratings, dimensions, and material specifications of the original Grinnell pipe hangers, ensuring safe and reliable performance in your system.
Q: How do I use the chart if I only have an old hanger catalog?
A: Simply look up the specific figure number from your old hanger catalog in our table. The chart will direct you to the corresponding PTP part number for quick, accurate quoting and ordering.
Q: Does this chart cover all types of Grinnell pipe supports?
A: The chart covers a comprehensive range of standard Grinnell pipe supports, including clamps, shoes, restraints, and struts. If you have a highly specialized or custom part, our engineering team can assist you with a custom PTP match.
Q: Can I use these PTP replacements for new installations instead of Grinnell pipe hangers?
A: Absolutely. Many engineers specify PTP equivalents for new construction projects from the very beginning, relying on our robust fabrication capabilities as a direct, high-quality alternative to standard Grinnell pipe hangers.
