Security Storage Co., a Washington household moving firm, has reported 1976 profits of $184,000 ($2.12 a share) compared with $153,000 ($1.76) in 1975, as revenues rose 2 per cent to $5.19 million.

In a report to stockholders, chairman Robert L. Tull and president Robert E. Windham said the moving and storage market "was extremely competitive last year, and we foresee no change for 1977."

Despite higher costs for fuel, insurance, supplies and wages, regulated interstate moving rates were cut by about 8 per cent during the year to meet competition, they said.

A new subsidiary, Security International Corp., was formed last August to sell American products abroad. More recently, Security Storage purchased a 53 per cent interest in Control Laser Corp. of Pompano Beach, Fla., for $2.6 million.

Company officers said laser manufacturing "is far afield from moving and storage, travel, freight forwarding and our other services," but "we feel it is an excellent investment opportunity" because of a record of profitability and growth potential.
