Exterior Shutter Dogs

Exterior shutter dogs are both a fundamental component of the proper function of outside house shutters and an opportunity to personalize the presentation.

Exterior shutter dogs available in many different styles and patterns.

Shutter dogs, or tiebacks, consist of two primary components. The principle element floats parallel to the window in front of an open shutter. It revolves on a perpendicular supporting axle anchored to the facade of the house. The exterior shutter dog is intentionally asymmetrical so it naturally rests in a vertical position. Installed just beneath the open shutter, the tieback autonomously restrains an outstretched panel, then rotates horizontally to permit the release of the window shutter to close over the opening.

Some exterior shutter hinges, including Clarks Tip and Lull & Porter, self-lock when the shutters are ushered wide of the window. However, popular surface mount strap hinges are less dynamic, making exterior shutter dogs a vital accessory.

Shutter Dog Styles

Exterior shutter dogs are sold in an array of designs and patterns. The S-shaped scroll is most commonly applied throughout the United States. Other styles are more prevalent in defined regions.

In the New England states, hand-forged designs are used for historic preservation. Propeller-shaped and rat-tail colonial shutter dogs are prominent along the Eastern seaboard. Ornate flower, grape, or star forms enhance the character of both traditional and modern buildings. Dolphin, scallop, sea horse, or alligator shaped tiebacks are frequently adopted on coastal or lakeside homes.

Shutter Dog Installation

Shutter dogs should be installed after the shutters have been hung on exterior hinges. Only then can the proper mounting location of the shutter hardware be identified. Tiebacks should mount about 1/4 the width of the shutter from the outside edge and roughly 1-1/2 inches from the bottom. Occasionally, shutter dogs are incorrectly installed to the side of the shutter panel, which diminishes the effectiveness. Measure the precise mounting point of all tiebacks for exterior shutters being installed before drilling the first pilot hole.

One of three different methods can be used to install exterior shutter dogs, depending on building material and window structure. Lag-mount tiebacks are employed for most applications, which utilizes a bolt through the face of the shutter dog can adhere to hard or soft surfaces. The bolt will firmly tighten into a pre-drilled hole with a right-sized ratchet. A plate-mount tieback integrates well with relatively flat wood surfaces. When the first two options are not feasible,  a bent arm can extend from the window casing to support the hold back.

Alternatives to Exterior Shutter Dogs

Shutter dogs are not the only way to lock outdoor shutters in an open position. Historically, long hooks that connect to the window sill to an eye bolt in the shutter were employed. The same system is favored in some districts today.

For minimal visual impact, sleek bullet catches can screw to the face of the shutter. The receiving hardware is fastened to the house, which grasps the bullet when contact is made.

Faux Shutter Dogs

False shutter dogs are produced for exterior shutters installed in a stationary position. The faux hold backs can be added to enhance curb appeal but do not operate .
