Q: Can You Use the SRS SuperLock for Applications Other Than HVAC Piping?
A: While the SRS SuperLock was designed with HVAC linesets in mind, its durable construction and 44 lbs (20 Kg) load capacity make it a reliable choice for plumbing pipes. If you’re looking for a versatile indoor horizontal support, this one covers a lot of ground.

Q: What Size Threaded Rod Does the SRS SuperLock Work with?
A: The SRS SuperLock is designed to work exclusively with 3/8″ threaded rod. Before installing, you’ll want to confirm your rod size matches to get that secure, tool-free snap-on connection working as intended.

Q: How Do You Adjust the Level After Snapping the Clamp in?
A: Simply rotate the clamp along the threaded rod until you hit the right alignment. The hinge mechanism also lets you hold things in place temporarily while you make those adjustments, which makes the whole process a lot more manageable.

Q: Is the SRS SuperLock Approved for Outdoor Use?
A: No, the SRS SuperLock is rated for indoor use only. If your project involves outdoor or exposed environments, you’ll want to look at other support options that are built to handle the elements.

Q: What’s the Maximum Load the SRS SuperLock Can Hold?
A: Every size in the SRS lineup carries an allowable static load of 196N, which works out to 44 lbs (20 Kg). That gives you solid, dependable support for most standard HVAC and plumbing pipe applications in horizontal indoor settings.

Q: Do You Need Special Tools to Install the SRS SuperLock?
A: Not at all. The one-touch clip design means you can snap the clamp right onto a 3/8″ threaded rod by hand. It’s a clean, tool-free install that saves time and simplifies your workflow on every job.
