Most steel struts have a maximum working load of 4,000 lbs. The TeleCrib® struts have a max working load of 18,000 lbs with a greater than 2:1 safety factor. Because they are composite, they are nearly impervious to environmental or chemical corrosion, do not conduct electricity, and have exceptional impact resistance. If you need lifting capabilities, our removable Strut Jack fits on any TeleCrib® strut, turning it into an 8,000 lb ram.
