FAQ
FAQ
What is this protective sleeve used for?
It protects the edge of an 8 mm hole by keeping the screw from touching the panel directly. This helps reduce stress and surface damage during mounting.
Which hole size does it fit?
It is designed for an 8 mm drilled hole. For best results, use clean, burr-free holes.
What is the outside diameter of the sleeve?
The outer diameter is 12 mm. This provides a wider contact area around the hole for added protection.
How thick is the sleeve collar?
The collar thickness is 1 mm. This gives a neat finish while still protecting the panel surface around the hole.
How do I install the sleeve?
Press the sleeve into the drilled hole until it sits flush. Then install your mounting hardware through the sleeve as usual.
Is it suitable for glass and acrylic (plexiglass) panels?
Yes, it is commonly used with glass and plexiglass sheet applications. It helps protect the material around drilled holes during assembly.
Can I use it with sign standoffs?
Yes, it’s a practical add-on for standoff installations where a screw passes through a panel. It helps keep the mounting point tidy and protected.
Does it prevent scratches from metal fasteners?
Yes, it creates a protective barrier between the screw and the panel. This can reduce rubbing and visible marks around the hole.
How do I clean and maintain it?
Wipe with a soft cloth and mild cleaner during regular sign cleaning. Avoid abrasive tools to keep the surrounding panel looking sharp.
Can it be reused after disassembly?
In many installations it can be reused if it’s removed carefully and remains undamaged. Check the fit before reinstalling to ensure it still sits securely.
