Pg 1631 of the mcmaster-carr industrial catalog (cat #104) shows "straight"
ladders in glass, aluminum,wood. The alu 12' ladder goes for 112.98 and is
25 1/2" width - part #8007t23 . They also show a flared base one for 3 times
the price of the straight. You might also try msc direct or graingers (or
