Overview
This SK4001-BL clamp weighs about 0.29 kilograms, roughly 10 ounces, putting it in the range of a small hand clamp rather than a heavy duty bar clamp. The brand field lists only the numeral 6, which is not a usable manufacturer name.
Beyond the model number SK4001-BL and its light weight, the listing supplies almost nothing else to go on, and the brand field is not a real company name. What stands out is demand: it sold at a rate of 600 units in the past month, well above most listings in this batch.
