Kraloy 29575 – Frequently Asked Questions
1) What size conduit does the Kraloy 29575 base spacer hold?
The Kraloy BS5545 base spacer is sized for 4 inch and 3 inch duct, so it positions those two conduit sizes in the same run. If your duct bank uses other trade sizes, you need the matching spacer for that diameter instead.
2) How do these duct bank spacers hold the conduit, and do I need extra hardware?
Snap fit. The conduit presses into the saddle and is held without clips or ties. The spacer also has integral holes for fastening and stabilizing the base row, and molded rebar slots so rebar drops straight in during placement.
3) Can I build a wider duct bank than one spacer covers?
Yes. Different sized Kraloy spacers are made to be grouped side by side to make up whatever width of duct bank the drawing calls for, so a 4x3 unit can be ganged with other sizes rather than limiting you to a fixed configuration.
4) Is a base spacer the same thing as an intermediate spacer?
No. The BS5545 is a base spacer, the bottom course that sits on the trench floor and carries the first layer of duct. It has fastening holes to anchor and stabilize it there. Stacking spacers for the layers above it are a separate item.
5) What is this Kraloy spacer made of, and will it hold up in a concrete-encased trench?
Molded ABS, black. It is a non-metallic spacer, so nothing in it rusts against the concrete pour, and the design is shaped to adapt to the contours of an uneven trench bottom rather than needing a flat prepared surface.
6) Is the Kraloy 29575 spacer made in North America for buy-domestic job requirements?
It is manufactured in Canada and carries NAFTA designation. For federal or state jobs with a domestic sourcing clause, check whether your specification accepts Canadian origin, since requirements vary by contract.
7) What part number do I order for the Kraloy 4 inch by 3 inch Superduct base spacer?
Order Kraloy 29575, catalogued as BS5545. That is the 4 inch by 3 inch base spacer in the Superduct line.
