HoldRite products and EPD coverage snapshot
HoldRite is a familiar name to MEP pros for pipe supports, DWV testing, firestop, and water‑heater accessories. The product catalog is broad and practical. What is less visible is how well this portfolio is covered by Environmental Product Declarations, the credential that increasingly decides whether a product gets specified when carbon accounting shows up on a project brief.
Who they are
HoldRite, part of RWC’s family of brands, focuses on engineered plumbing and mechanical solutions used across residential and commercial projects. Their gear shows up in healthcare, education, hospitality, multi‑family, and more.
What they sell
Core lines include pipe supports and brackets, HydroFlame cast‑in firestop sleeves and accessories, firestop sealants and putty pads, DWV testing systems under the TestRite name, acoustic isolation components, water‑heater stands and straps, and appliance boxes. It is a wide portfolio with SKUs in the hundreds.
How focused is the lineup
They are not a pure play in one niche. Expect five to seven distinct product families that map to typical MEP scopes rather than a single specialty. That helps distribution but raises the bar for environmental reporting because each family can fall under a different PCR and operator workflow.
EPD coverage today
As of December 19, 2025, we could not locate published product‑specific EPDs for HoldRite across major public registries and operator libraries. That includes their visible best sellers like HydroFlame firestop sealants and sleeves, and everyday staples like isolation strut clamps. If an EPD exists behind the scenes, it is not easily discoverable where specifiers usually look. That discoverability gap matters when design teams are moving fast.
Where competitors are showing up with EPDs
Pipe supports and clamps are a good example. Walraven announced EPDs for 39 clamp products in 2025, giving specifiers transparent data at the exact point of substitution (Walraven, 2025) (Walraven, 2025). MÜPRO published an EPD for galvanized support channels, another common swap where an engineer can meet performance and tick an enviromental box at once (MÜPRO, 2025) (MÜPRO, 2025). On the piping side that pairs with supports, producers like Wheatland and the Steel Tube Institute offer EPDs for fire sprinkler and HSS related pipe, which many project teams already reference (Wheatland, 2025) (Wheatland, 2025) and (Steel Tube Institute, 2025) (Steel Tube Institute, 2025).
A likely missed spec today
HoldRite’s Variable Closure Isolation Strut Clamp is a versatile, noise‑reducing fastener used everywhere from riser rooms to lab retrofits. We did not find an EPD for it. Walraven’s clamp range now carries multiple clamp EPDs, which means a designer aiming for LEED v5 material transparency can document that choice in one click. In tight bid windows, the product that comes with a ready declaration often gets penciled in first.
Firestop is moving too
Firestop sealants and joint products are beginning to publish EPDs in Europe under EN 15804. Examples include Firetect and Firesafe branded acrylics with valid declarations in EPD International, which signals a category trend even if North American brands have been slower to post public EPDs at scale (EPD International, 2023–2025). When these appear in US‑facing catalogs, the gap will feel bigger on mixed‑use and healthcare work.
Who HoldRite meets in the spec arena
- Firestop and sleeves: Hilti, 3M, STI Firestop, RectorSeal
- Pipe supports and clamps: nVent Caddy, Walraven, MÜPRO, ZSi‑Foster, Sioux Chief
- Water‑heater accessories and boxes: Oatey, Sioux Chief, Watts Each of these categories already has peers with at least some EPD coverage, which changes how “like‑for‑like” substitutions are judged.
Why EPDs matter commercially now
Without a product‑specific EPD, designers often must use conservative defaults in carbon accounting, which can nudge them toward an alternative with verified data. Teams rarely slow a schedule to wait for documentation. An EPD removes that friction and protects share in projects that apply LEED v5 style transparency criteria. One mid‑sized project win can repay the credentialing effort.
Fast path for HoldRite to close the gap
- Prioritize EPDs for the top twenty revenue or spec‑critical SKUs in supports and firestop. These are high frequency line items where substitutions happen.
- Pick the prevailing PCRs competitors use so apples‑to‑apples comparisons are clear. A good LCA partner will map the competitor landscape and operator options, then recommend the path of least resistance.
- Make data collection painless for manufacturing, quality, and sourcing teams. White‑glove collection paired with a disciplined project plan is what compresses timelines.
- Publish where specifiers search and link directly from product pages. If it cannot be found in seconds, it does not help in precon.
What we would watch next
If HoldRite adds EPDs for clamps, cast‑in sleeves, and a flagship sealant, they will remove the single biggest barrier to automatic inclusion on transparency‑minded projects. The engineering credibility is already there. Make the paperwork just as strong and the spec will follow.
Frequently Asked Questions
Which HoldRite product families are most strategic for first EPDs?
Pipe supports and brackets, cast‑in firestop sleeves, and one flagship firestop sealant. These are high‑volume items with frequent substitutions, so a published EPD removes friction at spec time.
Do competitors in pipe supports really have EPDs today?
Yes. Walraven states 39 clamp products now carry EPDs (Walraven, 2025). MÜPRO has an EPD for galvanized support channels that frequently substitute into similar scopes (MÜPRO, 2025).
What credible sources can specifiers cite for piping EPDs paired with supports?
Steel Tube Institute hosts industry‑average EPDs that include ASTM A795 fire protection pipe among others (Steel Tube Institute, 2025). Wheatland publishes EPDs for fabricated fire sprinkler pipe that are easy to download (Wheatland, 2025).
Does LEED require new EPDs every time PCRs update?
No. When a PCR expires, the next renewal cycle should use the updated PCR. In the meantime, a valid Type III, third‑party‑verified EPD remains acceptable within its stated validity window.
What if a category lacks a perfect PCR fit?
Many program operators provide construction‑products PCRs that work as a fallback. A strong LCA partner will benchmark competitor PCR choices and steer to the most accepted route.
