From the door schedule, what frame material is scheduled for door D480?
Correct Answer
D) HM
On Sheet A-638, Mark D480 is the correct row; the Frame cell in that row shows HM.
Why This Is the Correct Answer
On Sheet A-638, Mark D480 is the correct row; the Frame cell in that row shows HM.
Why the Other Options Are Wrong
Option A: AL
Choice A is the frame value shown for D481, not for D480.
Option B: SS
Choice B is the frame value shown for D482, not for D480.
Option C: WOOD
Choice C is the frame value shown for D483, not for D480.
Memory Technique
Keep D480 and Frame paired; any other row-column crossing is a false read.
Reference Hint
Open Sheet A-638 in the plan packet, find Mark D480, then move horizontally to the Frame column.
