- Barely visible blocks are great for use in mirror installations
- Widely used in frameless shower installations
These clear plastic setting blocks are especially suited for use where black neoprene or thermoplastic rubber setting blocks are undesirable, such as mirror or 'all-glass' frameless shower door installations. They are barely visible in the bottoms of mirror channel, or on the bottom of sliding track H-Bar. These clear plastic setting blocks make glass leveling very simple in shower enclosures.
