A single-acting swing door is 36″ wide. The door frame is made of rabbeted stock. What length should the head jamb be?


A. 36 1 1/16″
B. 36 19/32″
C. 36 3/32″
D. 36 3/16″

Is it A?

To determine the correct length of the head jamb, we need to understand the concept of a swing door and the dimensions involved.

A swing door is a door that opens by swinging on hinges attached to one side of the door frame. In this case, we are specifically dealing with a single-acting swing door, which means it only swings in one direction.

The width of the door is given as 36 inches.

When it comes to measuring a door frame made of rabbeted stock, we need to consider that rabbeted stock is usually thicker than the actual width of the door. This is because it includes the depth of the rabbet, which is a recess or groove cut into the edge of the stock to receive and hold the door.

To find the correct length of the head jamb, we need to account for the width of the door and the thickness of the rabbeted stock.

Looking at the given options:

A. 36 1 1/16″
B. 36 19/32″
C. 36 3/32″
D. 36 3/16″

We need to find the length that accounts for the thickness of the rabbeted stock. However, the options provided do not give any information about the thickness of the stock. Without this information, we cannot accurately determine the correct answer.

Therefore, we cannot definitively say that option A is correct.
