Window Strike Plate

A Window Strike Plate, also known as a Window Keep, is a small but essential piece of hardware that is installed on the window frame, typically near the lock or latch. It provides a secure connection point for the window lock or handle, ensuring that the window remains firmly closed and cannot be forced open from the outside. Some strike plates also come with features that restrict the amount that a window can be opened, providing added security and safety benefits. With different sizes of strike plates available to fit various window types and sizes, they can easily be replaced if they become damaged or worn over time. At MB DIY, we understand the importance of a reliable window strike plate, including uPVC window keeps, in enhancing the security of your property. Discover how the right strike plate can provide you with peace of mind and ensure that your windows are well-secured against potential intruders.


Types of Window Keeps: How to Identify the Right One

There are several different types of window keeps available, each with their own unique features and benefits. One type of window strike plate is the mushroom keep, which is named for its distinctive shape. Another is the corner keep, which is typically used in conjunction with multiple shootbolt locks for added security. While a shootbolt keep is another type that is used in conjunction with a single shootbolt lock. Whichever type of window Strike Plate you’re looking for, at MB DIY, we will have something stored for you.

Window Shootbolt Keep

A window shootbolt keep is a type of strike plate that is designed to be used with shootbolt locks. This is a common type of locking mechanism that is typically found on uPVC windows. The shootbolt keep is usually installed on the window frame and features a slot or an opening that is designed to accommodate the shootbolt. It extends from the window sash and interacts with the keep to firmly shut the window.

Window shootbolt keeps are an essential part of any uPVC window that uses shootbolt locks. They provide the necessary support as well as security for the locking mechanism. Without a properly installed shootbolt keep, the shootbolt lock may not be able to engage with the window frame properly.

Window Mushroom Keep

A window mushroom keep is a type of strike plate that is designed to be used with mushroom-shaped window locks. Most of these locks have a pin that sticks out and fits into a slot in the window frame. This creates a secure and effective locking mechanism. The mushroom keep is installed on the window frame and provides a secure connection point for the lock to engage with, ensuring that the window is held securely in place.

Window mushroom keeps are typically used on uPVC windows but can also be used on other types of windows that feature mushroom-shaped locks. They are particularly useful for providing additional security and preventing forced entry. The unique shape of the lock and keep combination makes it more difficult for would-be intruders to tamper with or force open the window.

Window Shootbolt Corner Keep

A window shootbolt corner keep is a type of strike plate that is designed to be used in conjunction with shootbolt locks on uPVC windows. This type of keep is installed on the corner of the window frame and features a series of slots or openings that are designed to accommodate the shootbolts. They protrude from the window sash and make contact with the keep to firmly shut the window.

Window shootbolt corner keeps are usually used when more than one shootbolt lock is needed to protect the window to the right level. The corner keep provides a secure and stable connection point for the shootbolts. This is to make sure the window is secured firmly in position, which may be extended and engaged at the same time. Window Shootbolt Keep is especially useful for larger windows or windows in high-risk areas.
