## Question

Draw plan and vertical section of a panelled door shutter.

## Short answer

A panelled door shutter 1.0x2.1m with 40mm thickness has frame 100x75mm, styles/rails 100x40mm (lock rail 150x40, bottom rail 200x40), panels 15-20mm thick in 12mm grooves. Mortise and tenon joints glued and wedged. Three 100mm butt hinges placed 150mm from top, bottom, and centre; bottom clearance 10-12mm.

## Answer

A panelled door shutter 1.0 m x 2.1 m is shown below, with a frame of 100 x 75 mm and a shutter 40 mm thick.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. What thickness are the panels of the shutter?
   A. 40 mm
   B. 75 mm
   C. 5 mm
   D. 15-20 mm
   Answer: D. Panels are 15-20 mm, while the shutter is 40 mm thick. (Key point: Panel thickness)

2. Why are panels held in grooves rather than fixed rigidly?
   A. So they are free to expand and contract
   B. To make them removable for painting
   C. To increase the lock rail width
   D. To avoid using hinges
   Answer: A. Grooves of 12 mm depth let the panel move with moisture changes. (Key point: Panels free to expand)

3. How many hinges are used and where?
   A. Two, at the top and bottom edges
   B. Three, at 150 mm from top and bottom and at the centre
   C. Four, equally spaced
   D. One, at the centre
   Answer: B. Three 100 mm butt hinges are used in this arrangement. (Key point: Hinges)

4. Which rail is the deepest, and why?
   A. Top rail (200 mm), to carry the lock
   B. Lock rail (200 mm), for hinges
   C. Bottom rail (200 mm), strong against kicking
   D. Frieze rail (200 mm), for glass
   Answer: C. The bottom rail is 200 x 40 mm for strength at floor level. (Key point: Bottom rail size)
