Frequently Asked Questions

AI
Climbing blockers are safety devices used in arboriculture and caving to control rope movement and arrest falls. Sliding door pulleys are mechanical rollers that facilitate the smooth opening and closing of heavy doors or cabinets. They serve entirely different safety and utility functions.
Stainless steel offers superior strength and heat resistance for heavy lifting or industrial winches. Nylon wheels are preferred for sliding doors because they operate more quietly and resist corrosion in humid environments. Choose based on your load weight and noise requirements.
Generic rope grabs may lack the rigorous safety certifications required for professional use. For arborist work, always use equipment rated for life safety, such as those from established brands like Petzl. Using uncertified gear for vertical access poses significant fall risks.
