W.W. Grainger Inc., a supplier of industrial maintenance and safety products, said Friday that daily sales in February rose 11 percent compared with a year ago.

Acquisitions contributed one percentage point to the gain, with foreign exchange contributing another point. Excluding those factors, organic sales were up 9 percent over a year ago, due to rising sales volume and prices, the Chicago-based company said.

U.S. sales rose 8 percent and sales in Canada jumped 24 percent, the company said.

Shares of Grainger rose $2.07, or 1.5 percent, to $136.48 on Friday.
