Building a Part Number
Full Bar Length = 8.00ft
Examples:
If you wanted to simply order extrusion # 61565 in standard bar form, the part number would be:615651F00000. The unit price
would be sold by the foot.
If you wanted extrusion 61565 cut to a length of 6.500" and black anodized, the part number would be:615653B06500. The
unit price would be by the piece.
If you wanted extrusion 61565 cut to a length of 14.725" and a wash finish, the part number would be:615653U14725. The unit
price would be by the piece.
*For unfinished extrusions with cut lengths other than half bar, the finish designation is a U.
Standard Aavid Thermalloy parts require all 13 positions to be complete.

avid Thermalloy has over 10,000 extrusion profile designs on file, most with the extrusion die already available. These parts have
minimum order requirements and longer lead times, but may be cost effective compared to a new design.
We offer several options for those applications which require a more unique solution. Challenge us with your thermal
requirements - we can design custom solutions.
