Joist Clips That Support Stronger, Faster Overhead Installations
At Docs Industries, we know that when you specify or install overhead support hardware, every component matters. A joist clip must be secure, quick to install, and reliable under real-world loads. That’s why we design our joist clips with spring steel construction and provide practical solutions for hanging ceiling wire, jack chain, and threaded rod, supporting a broad range of applications in structural and commercial construction.
Why Our Joist Clips Matter
Overhead support is only as good as its attachment point. If the connection isn’t straightforward, labor costs rise and productivity drops. Our joist clips solve these challenges with proven strength and speed. They are designed for secure, repeatable attachment to purlins and beam flanges, helping engineers simplify the specification process and contractors work efficiently.
Engineering Benefits
Versatile Fit
Our clips accommodate flange thicknesses from 1/8″ to 1/4″, covering most conditions found in commercial and industrial settings. The C Purlin Clip works with vertical flanges, while our Z Purlin Clips (including both ADOC14 and ASC14) are made for diagonal or angled flanges. You select the right clip for the structure, no compromises.
Durable Spring Steel
Each clip is made from resilient spring steel to provide strong clamping action. This boosts field productivity, hardware that installs confidently stays in place and supports overhead loads reliably at scale.
High Load Capacity
Our joist clips are designed as an integral part of the load path in overhead systems. By clamping firmly to the supporting member, the clip acts as a stable connection, supporting the required suspended load. Always consult product testing, project requirements, and code before finalizing allowable loads.
Purpose Built Installation Tools
Installation speed and consistency make a real difference. Our HOIT AL and HOIT S installation tools are engineered for quick, safe installation of our spring steel clips, helping crews maintain quality and reduce installation time across all ceiling and beam conditions.
Compliance and Specification Considerations
Confirm Flange Thickness
Our clips are intended for 1/8″ to 1/4″ thick flanges. Verifying flange thickness before installation is vital for security and code compliance.
Select the Right Clip
Use C Purlin Clips for vertical flanges and Z Purlin Clips for diagonal or angled flanges. Proper selection ensures reliable performance.
Match to the System
Our clips attach ceiling wire, jack chain, and rod hanger assemblies. Specify the attachment method best suited to the system being installed, mechanical, electrical, fire protection, or ceiling-related.
Validate Load and Code
Engineers should confirm allowable loads, safety factors, and code compliance using proper documentation and project criteria. Final selection must comply with governing codes and site conditions.
Use Correct Installation Tools
Proper installation boosts field efficiency and inspection outcomes. Our HOIT AL and HOIT S tools help deliver consistent attachment quality at each point.
Applications
Suspended Ceilings
Our clips provide ideal attachment points for ceiling wire in commercial buildings with purlins or beam flanges overhead.
Mechanical & Electrical Support
Hang light mechanical or electrical elements quickly, our clip and rod hanger options provide practical, labor-saving alternatives to field-made supports.
Jack Chain Hangers
Perfect for jack chain installations, our purlin clips simplify connections for a wide range of general construction needs.
Retrofits & Tenant Improvements
Fast installation is especially important in retrofit and tenant improvement projects. Our clips cut disruption and boost crew mobility in tight spaces.
Industrial & Warehouse Construction
Warehouses and industrial projects often require both vertical and angled flange solutions. Our product line ensures the right fit for any overhead job.
