How is the BARTOO spacer built and what materials are used?

• Manufactured to standard tolerances to allow direct replacement in many applications.

How easy is installation and what hardware do I need?

No special tools are necessary beyond basic hand tools and any original mounting studs or bolts.

• Direct-fit replacement in compatible 5-1/8" openings; often uses existing studs or bolts.
• Use a thin gasket or sealant if your application needs improved sealing.
• No special tools required; basic wrenches or socket set suffice.
