On a kitchen install, plans call for 18" silestone bar, set atop 2x4 1/2 wall. 5" will be over half wall & backsplash of counter, then 13 inch overhang. Customer doesn't want brackets to support overhang-

Is there a way to fix the bar to the 2x4 top plate?

Is silestone strong enough to support itself on a 13" overhang?

Any other suggestions to prep for this bar?

I have the same question. Did you get a reply?

[URL=http://www.precisioncountertops.com/documents/pcGenericContract.pdf ]Silestone supplier[/URL]: "Silestone can extend 12” unsupported without cutouts provided it is on a full depth (24") cabinet."

DIY forum post "When using the 1 1/4" thick tops, up to 12 inches is acceptable."

"Adequate support: The surface type and material thickness dictate the amount of overhang permitted on a countertop. The countertop can support an overhang of without additional brackets or corbels:

* 6" (Acrylic Countertop)
* 6" (2cm Stone Countertop)
* 10" (3cm Stone Countertop)

However, at least 70% of the total countertop must be supported by cabinets, an island, knee wall, etc. All overhangs in excess of those previously mentioned will require corbels or brackets. All support brackets and corbels must be installed prior to the field template. New or existing cabinets must be structurally sound to withstand the weight of the countertop."
