I need to replace one sliding door roller guide.2 1/2" long, 3/4" wide, 1 1/16 high, 1" diameter metal wheel. Has a wheel adjustment screw. It is stamped "DEL MAR ENG. LONG BEACH,CAL." PAT. 3,670,357. This a double thermal glass aluminum frame door 4' x 6' 8". Very heavy probably manufactured in the 70's.

81-077 appears to be identical except for the 1 1/4" steel roller. If the dimensions of the housing are the same I think it could be made to work. The trick would be to get the door to recess far enough into the overhead track for the larger roller to clear the sill guide. I am temporarily without my camera and cannot submit a picture until next week when my wife returns
