Home SecurityDoors, Frames & Locks

All locks are not created equal!

A few seconds ... that’s how long it takes the average burglar to get into a home.

PRP 52Revised – May 2008

Door systemsThink about it: it can take less time for a burglar to forcibly break into your home than it does for you to fumble for your keys and open the door that way. A burglar, with one forceful, well placed kick, can break open the average door. Kicking in the door requires no special tools and surprisingly, makes very little noise.

Doors & FramesGood door security starts with the proper installation of the frame and a good quality door without glass near the lock. Skipping this step in favour of installing a good quality lock, is the equivalent of securing a paper lunch bag with a padlock.

Frames

1. Wood Frames (exterior door only)

(a) All exterior door frames should be set in frame openings constructed of double studding, including garage doors, but excluding overhead doors.

(b) Door frames should be installed to close tolerances (0.5 cm or 0.2 inches) inside the rough opening. An alternative is filler plates* around frames at critical areas, including all locks, latches and hinges.

* Filler material should extend 30 cm (12 inches) above and below the strike plate area, and 7.5 cm (3 inches) above and below the hinges. Filler material should consist of solid hardwood blocks.

Filler plates add to the integrity of the frame, reduce the gap between the door frame and the wall studs (a potential pry area), and allow for a

strong structure to support the required security hardware.

Doors

1. Wood All exterior doors, including

exterior and interior garage doors, should be of solid wood construction such as high density particle board, solid wood, or wood block core. No panels should exist on the doors.

2. steel Steel doors should be of steel

grid, or steel edge construction with a minimum steel thickness of 20-gauge.

Some steel doors are equipped with wood frames that are steel clad. Although these frames may offer a greater degree of protection, they should still be considered as wood frames and installed accordingly.

A good starting point is to look for doors that meet the following standards:

(a) The Canadian General S t a n d a r d s B o a r d ’ s specification for wood flush doors (CAN / CDSB 0132.2-M).

(b) The Canadian General S t a n d a r d s B o a r d ’ s specification for insulated steel doors (CAN / CDSB 82.5-M).

Door strikesThe strike is a crucial part of the locking mechanism. Its purpose is to reinforce the frame allowing the lock to do its job.

strikes For WooDen FramesStrikes should be of a minimum 5mm (1/8”) thick solid metal with four off-set screw holes. Screws securing the strike should be a minimum of 8.75 cm (31/2”) long and penetrate a minimum of 2.5 cm (1”) into the supporting wall structure regardless of filler thickness.

escutcheon platesOnce the strike is properly secured, the force of any attack is transmitted to the door. Most residential doors, including steel faced insulated doors, are built using wooden edges (stiles) that split easily under the force of attack. To strengthen the door, an escutcheon plate is required.

a minimum of 10.6 cm (4 1/4 inches) length carriage or hex bolts mounted through the door and into the escutcheon plate. The lock shall incorporate the following features:

• drill-resistant cylinder • twist-resistant cylinder with tapered, hardened steel or

free-spinning cylinder guard • hardened steel locking bolts

note: Rim-mounted locks shall be used in conjunction with

angle strikes.

Double DoorsIn addition to the above mentioned lock, double doors also require added hardware that may be difficult to install.

1. sliding bolts The inactive leaf on a double door

should be provided with heavy duty slide bolts, top and bottom. All slide bolts shall penetrate a minimum of 2.5 cm (1 inch) when thrown and use a high security strike. This protection is not required when the slide bolt penetrates into concrete.

2. escutcheon plates All slide bolts and locks shall

be protected with an escutcheon plate. (Note: This may be difficult to accomplish due to weather stripping.)

note: If at all possible, avoid using double doors unless the manufacturer has

specifically designed them to forced entry specifications. If retrofitting, contact Crime Prevention Services for alternatives that might help.

Double cylinDer DeaDboltThe Peel Regional Police DO NOT RECOMMEND the use of double cylinder deadbolt locks on doors due to the exit requirements in an emergency.

If there is glass within 40 inches of a deadbolt lock, the glass itself should be fortified or replaced with a UL/ULC or other suitable standard burglary resistant glazing product.

home security – Doors Frames & locks Fact sheet

All exterior doors should have escutcheon plates with back plates or wrap-around door channels installed around any deadbolt lock. Plates are to be secured from the inside with 1.9 cm (3/4 inch) carriage or hex bolts that cannot be removed from the exterior. The small screws that are supplied with most escutcheon plates should be replaced with bolts. (Redrilling the holes in the escutcheon plate may be required.)

lockstubular Deadbolt locksDeadbolt locks should have the following features: • minimum of 5.6 cm (2 1/4 inch)

interlocking bolts to hold the cylinder together

• pick-resistant cylinder • drill-resistant cylinder • twist-resistant, tapered hardened

steel, or free-spinning cylinder guard

• hardened steel bolt, minimum 2.5 cm (1 inch) long (when thrown) and shall incorporate a saw-resistant feature.

Vertical Drop DeadboltsVertical drop deadbolt locks can be used in the following situations: • double doors • doors in which the frame cannot

be secured against spreading (i.e. double studding and filler plates)

• circumstances where minimum length screws cannot be installed, such as a window next to the frame.

Rim mounted vertical drop deadbolts should be installed on these doors with
