A frame cramp is a small metal device used in construction to connect two or more timber or steel framing members together. It is usually made of galvanized steel or stainless steel and comes in a variety of sizes and shapes, including L-shaped and U-shaped.

Frame cramps are typically used in applications where one framing member needs to be secured to another, such as securing roof rafters to wall plates or securing floor joists to foundation walls. They are installed by attaching them to one framing member with screws or nails, then securing the other member to the cramp with additional screws or nails.

There are many benefits to using frame cramps, including:

1. Increased structural stability: Frame cramps provide a strong and secure connection between framing members, increasing the overall structural stability of the building.

2. Versatility: Frame cramps come in a variety of sizes and shapes, making them suitable for a wide range of applications and framing member sizes.

3. Easy installation: Frame cramps are easy to install and can be attached to framing members with standard screws or nails.

4. Durability: Frame cramps are typically made from high-quality steel and are designed to withstand the stresses and strains of building construction and use, ensuring long-lasting durability.

5. Cost-effectiveness: Frame cramps are a relatively inexpensive tool that can improve the overall strength and stability of a building.
