This jack's footplate is more stable than that caster wheel and block you're using. Premium zinc finish has a 500-hour salt spray rating - great for trailers near saltwater. Total lift includes a 13-1/2" drop leg. Made in the USA.
Keep your ball mount, tow bar, bike rack, cargo carrier, or other hitch-mounted accessory stable and rattle-free with this easy-to-use clamp. No tools needed, just tighten the clamp with the built-in lever and then pop it down to secure.
