Radiant Solutions Company S5N Roof Clamp 5-Pack — Non-penetrating Standing-Seam Clamp with M8 Thread, Made in USA

The Radiant Solutions Company S5N Roof Clamp 5-pack is a non-penetrating standing-seam metal roof clamp engineered to secure heat cable, snow guards, solar attachments and other accessories without piercing the roof panel.

Designed to fit common 1" nail-strip standing seams and similar profiles, the S5N clamp provides a durable, low-profile anchor point by dimple-setting the seam material with bullet-nosed set screws rather than penetrating it. Each pack contains five precision aluminum clamps, ten stainless steel bullet-nosed set screws and five M8 stainless bolts for threaded attachments. The clamps are made in the USA, carry a material and workmanship lifetime warranty, and are intended for demanding roof-mount tasks where weather-resistant, secure attachment is essential.

How does the S5N clamp attach to a standing seam without drilling?

The S5N uses angled bullet-nosed set screws that press into the seam, creating a shallow dimple that locks the clamp in place without penetrating the panel or compromising corrosion resistance. This mechanical grip squeezes the seam against the inner wall of the clamp to produce a strong, non-destructive hold that resists vertical and lateral loads.

• Two T-30 Torx round-point stainless set screws per clamp for secure, damage-free grip.
• Set screws create a dimple rather than a hole, preserving roof weatherproofing.
• Simple torque-only installation — no drilling, welding, or special fasteners required.

Which roof profiles and accessories work with this 5-pack?

The S5N is tailored for 1" nail-strip type standing seams and similar rib dimensions; it matches many widely used profiles from major manufacturers. A threaded top hole accepts M8 bolts, so you can mount heat cables, snow guards, solar clips and other accessories directly to the clamp.

• Compatible with 1" nail strips like Easy Lock, Skyline, Meridian, FF100 and similar profiles.
• Top-threaded hole accommodates M8 bolts for solar mounts, snow retention, or cable clips.
• Pairs with S5-SR clips and other accessory hardware for heat cable management (sold separately).

What comes in the box and what tools are required?

Each 5-pack includes five aluminum S5N clamps, ten stainless steel bullet-nosed set screws and five stainless steel M8 bolts. Note that the T-30 Torx bit is not included, so you’ll need a T-30 Torx driver or bit on hand for installation.

• Includes: 5 clamps, 10 bullet-nosed set screws, 5 M8 stainless bolts.
• Required: T-30 Torx bit or driver (not included) and a torque wrench or driver for consistent tightening.
• Quick install: position clamp, tighten set screws to seat the clamp, then add your attachment to the threaded top.

How durable is the S5N and what warranties apply?

The clamp body is crafted from corrosion-resistant aluminum and paired with stainless steel hardware for long-term outdoor performance. Radiant Solutions Company manufactures these clamps in the USA and backs them with a lifetime material and workmanship warranty, offering reassurance for permanent roof-mounted installations.

• Aluminum clamp body with stainless steel set screws and bolts for weather resistance.
• Made in the USA with a lifetime material/workmanship warranty.
• Engineered for repeated loading scenarios including snow retention and solar arrays.

Who is this for? The S5N 5-pack is ideal for contractors, roofers and experienced DIYers installing heat-trace cables, snow guards, solar mounts or other attachments on compatible standing-seam metal roofs. Choose this clamp when you need a reliable, non-penetrating anchor point that’s quick to install, compatible with common 1" nail-strip profiles, and supported by a long-term warranty. Remember to have a T-30 Torx driver available — it is required for tightening the provided bullet-nosed set screws.
