FAQ
Questions, answered straight
What does single-cast actually prevent?
Welded handle bells can develop play or fail at the joint under years of hard set downs. A single casting has no joint, which is why serious brands lead with the claim and why we verify it in maker documentation.
How do I stop cast iron rusting in a garage?
Wipe chalk and sweat off after sessions, store bells off bare concrete, and touch up coating chips early. A light oil wipe on bare competition handles helps in humid climates.
