For those with a pop-top and a built in skylight, the lock/support bar may wear out from use, causing the bar tolerance against the lock/unlock button to widen.  This may cause the following:
 - Bar rattling against the lock/unlock button leading to annoying vibrations and noises.
 - The bar tension being not as tight as it used to be may cause the skylight hatch to vibrate and open ever so slightly, just enough to cause cross wind noises while driving.  Some owners have resorted to stuffing pool noodle foam pieces, folded towels, cheeseburgers, etc. between the bar and the lock/unlock button.  What this Bar Spacer provides is a more simple form factor that is compact and austhetically pleasing (in our humble opinion).
 
Before ordering, please measure the space between the bar and button in millimeters.  
 
Available spacer sizes are: 10mm, 15mm and 20mm
- If spacer size is much larger than 20mm, it is highly recommended that you have a factory technician inspect your skylight mechanisms for excessive wear or damaged/faulty parts.  This spacer will not prevent imminent catastrophic failures due to excessively worn skylight parts or same damaged parts.
- 3DTech bar spacers are not designed as a substitute for repairs and maintenance needed for a faulty/damaged skylight system.
- This design features a built in protective housing that helps minimize any unwanted button unlocking, from being accidentally pushed or bumped.  
- Made using thermoplastics that offer superior durability and strength, including high temp resistance and UV tolerance, due to the placement and exposure to direct sunlight.
