this mounting system will hold many different sizes and shapes of glass. i make these in two different sizes, this one holds up to 5/16” thick glass. these are sold as a pair to mount on your own base. the pegs will require a 5/16” hole to be drilled into whatever you are mounting them on. i also have a large selection of kiln dried, live edge wood in many different varieties. please contact for more information on availability of live edge bases. the tuning forks are made from hand fabricated steel that has been clear coated to prevent corrosion. when placing your glass into this system it will only require a slight twist to the tuning forks to gently snug your glass into position to hold it safely. the glass shown is by: karen boldossor, not included.
