Service entrance cap · 1 in rigid/IMC/EMT · clamp-on aluminium · Arlington 142
1 in clamp-on aluminium service entrance cap for rigid, IMC, and EMT conduit. Used as an overhead service entry point for conductors, with a weather-resistant body and trade listings suitable for Canadian commercial and residential work.
What this product is for
This 1 in (27 mm nominal trade size) clamp-on service entrance cap is used at the top of rigid, IMC, or EMT conduit where overhead service conductors enter a building. It helps provide a weather-resistant entry point and supports a clean service mast termination.
Use for
Use for overhead service entry installations, mast terminations, and conduit runs that require a clamp-on entrance cap on 1 in rigid steel conduit, IMC, or EMT. Commonly selected by electricians for residential services and light commercial service entrances.
Avoid for
Do not use on PVC conduit or on conduit sizes other than 1 in. Do not treat this fitting as a substitute for proper service entrance design, conductor sizing, or local utility and code requirements.
Best for
Best for contractors who need a die cast aluminium weatherhead style fitting with clamp-on installation for metallic conduit systems. A clamp-on style can help speed installation compared with more involved fitting methods when the conduit type and size match.
Installed in
Typically installed on exterior service masts in houses, small buildings, garages, shops, and similar overhead-fed services across Canada.
Why this product exists
Service entrance caps provide a protected entry point for incoming conductors and help reduce direct exposure to rain and debris at the conduit opening. This style is made for 1 in metallic conduit systems and is commonly specified where a clamp-on aluminium cap is required.
Compared with similar products
Compared with non-metallic service entrance caps, this type is intended for rigid, IMC, and EMT metallic conduit. Compared with other trade sizes, 1 in is chosen only when the conduit size and service design call for it. Always match the cap to the exact conduit type, trade size, conductor count, and local code requirements.
