What our Experts Think
-
Professional‑Grade Mounting Solution – The Spalding I‑Beam & Joist Clamps (301‑100) give you reliable hardware for securing backstop or support pipe assemblies to steel I‑beams and joists, crucial for gym and arena installations requiring strong structural connections.
-
Heavy Duty and Stable Support – Designed for structural applications, these clamps help distribute loads from suspended backstop systems evenly across beam and joist flanges, improving stability and reducing stress on individual connections.
-
Versatile Fit for Facility Use – Ideal for use in school, collegiate, or community gym setups where support framing must attach to existing structural steel without welding, preserving building integrity.
-
Simplifies Installation Workflow – Clamps make it easier to position and fasten backstop supports or accessories to open‑web joists or beams, speeding up installation and reducing reliance on specialist tools.
-
Enhances Long‑Term Reliability – Using dedicated beam and joist clamps helps maintain secure connections over years of use, minimizing movement or loosening that can occur with improvised or non‑engineered hardware.

Maintenance Tips
-
Inspect Before Use: Check each clamp for cracks, deformation, corrosion, or loose fasteners before every setup — a safe connection starts with sound hardware.
-
Tighten Properly: Ensure bolts and set screws are evenly tightened to seat the clamp firmly on the beam flange without overtightening, which can damage metal or threads.
-
Clean & Dry: Wipe clamps clean and dry after use to remove dirt, grease, or moisture; this helps prevent rust and keeps the clamping surfaces effective.
-
Lubricate Threads: Lightly lubricate threaded parts occasionally to prevent binding and wear — especially if clamps have moving screws.
-
Avoid Overloading: Always match use to the rated load and beam size, and never exceed the specified working load limit; improper loading can stress or deform clamps.
-
Proper Storage: Store in a dry, clean area when not in use — protecting steel parts from humidity and contaminants extends service life
