CleanTop^® II Breadboards

77 Series Breadboard

Our 77 Series CleanTop^® II Breadboard differs from the 78 Series only in skin thickness. The 1/8" (3 mm) skin offering provides a relatively high level of rigidity with a significant cost reduction. The 77 Series Breadboards are recommended when lighter weight construction is necessary or cost is critical.
