Crouse-Hinds UBM250HD – Frequently Asked Questions

1) Will a Crouse-Hinds UBM U-bolt work on EMT?
No. The UBM U-bolt is sized for rigid and IMC conduit. EMT of the same trade size has a smaller outside diameter, so the bolt will sit loose and will not clamp the pipe properly. Use an EMT-specific strap or clamp for thinwall.
2) Are these U-bolts rated for a hazardous or classified location?
No. The UBM heavy-duty U-bolt is rated for ordinary, non-hazardous locations only. If your run passes through a Class I, II, or III classified area, the support hardware needs to suit that classification, so check the area drawing before you spec these.
3) What size nuts and washers do I need for a 3/8-16 conduit U-bolt?
Threading on the UBM U-bolt is 3/8 inch-16 UNC on both legs, so it takes standard 3/8-16 hex nuts. The U-bolt itself is the fastener, so the nuts, washers, and whatever you are bolting through (strut, angle, a drilled plate) are separate items to add to the order.
4) Can I use electrogalvanized U-bolts outdoors or in a wet location?
Electrogalvanized iron gives corrosion resistance for general indoor and sheltered conditions. It is a thin plated coating, not hot-dip, so on a coastal site, a wash-down bay, a chemical area, or anywhere with standing moisture, specify hot-dip galvanized or stainless U-bolts instead.
5) Should I use a U-bolt or a one-hole strap to support 3 inch rigid conduit?
A U-bolt wraps the full circumference and is nutted on both legs, so it holds the pipe captive against a beam, strut, or channel and takes load from both sides. A one-hole strap only bears against a flat surface with a single screw and is meant for lighter runs on a wall. For 2 inch through 4 inch rigid or IMC on structure, the U-bolt is the support that carries the weight.
6) Do Crouse-Hinds UBM U-bolts meet NEC code for conduit support?
The UBM U-bolts are built to NEC/CEC standards, so they qualify as a conduit support method for rigid and IMC. The code still governs your spacing: securing within 3 feet of each box or fitting and at the support intervals the NEC gives for the trade size and the run. The bolt being compliant does not make the layout compliant.
7) Can I bolt these U-bolts to Unistrut channel?
Yes, and that is the common way they get used. Both legs are 3/8-16, so the U-bolt drops through a drilled plate, an angle, or a strut fitting and takes hex nuts underneath. Confirm the hole spacing on your strut fitting matches the leg spacing of the trade size you are ordering, since leg spread grows with pipe size from 2 inch to 4 inch.
8) Will an iron U-bolt cause corrosion against aluminum conduit?
Iron with an electrogalvanized plating on aluminum is a dissimilar metal contact, and in a damp location that pairing corrodes. The UBM is intended for rigid steel and IMC. If your run is aluminum rigid, use aluminum or stainless support hardware, or isolate the contact.
