Use Little Giant's Instrument Cart when you have fragile equipment to transport. The wood-composite shelves are cushioned and covered with non-slip vinyl fabric so sensitive devices won't shuffle around. Plus, they're non-conductive and sound-deadening so electronics won't be affected. A bumper on the top shelf protects walls and furniture from nicks and dings. Choose the type of caster that fits your needs: pneumatic, polyurethane or locking polyurethane.
