CleanTop Breadboard Lightweight - 35 x 47 in (Imperial)

The CleanTop lightweight series minimize both weight and cost. The formed, tapped holes are countersunk in a thin top of stainless steel. The holes are not drilled or punched, but fabricated in a way that effectively “thickens” the skin in a small ring around the threads. No inserts are used and the tapped holes are three threads deep.

These tops have relatively high levels of rigidity, as they utilize a standard steel core.  The breadboards are ideal when light loads are anticipated and low weight and or cost are the most crucial factors. The weight savings (50% less than the standard CleanTop breadboards) is derived only from the lighter gauge skins.
