Product Description
The Simpson MP14 1 in. x 4 in. Mending Plate from Simpson is a 20-gauge galvanized steel connector built for fast, straightforward wood-to-wood joining and light repair work. Featuring embedded prongs that lock into lumber without nails or fasteners, this mending plate offers a simple, reliable fix for general repair tasks where two wood members need to be held firmly together at a joint.
Key Features
- Nail-free prong installation - align the wood pieces with the arrows at the joint and hammer the plate to embed the prongs, saving time and eliminating the need for separate fasteners
- Versatile wood-to-wood connector - works across a wide range of general fix-up and light repair applications, making it a practical addition to any repair or maintenance toolkit
- Non-structural design - purpose-built for general mending and reinforcement tasks rather than load-bearing connections, so you get the right connector for the right job without overengineering light repairs
- G90 zinc galvanized coating - provides extra corrosion resistance, helping the plate hold up in environments where moisture exposure is a concern
- 20-gauge steel construction - offers a practical balance of strength and workability suited to non-structural wood connection and repair tasks
- Compact 1 in. x 4 in. footprint - sized to fit neatly at joints on lumber without excessive overhang, keeping repairs clean and unobtrusive
Why This Product
- Truly tool-light installation - because the prongs embed directly into wood with a hammer strike, there is no drilling, no screws, and no nail gun required, which means repairs go faster and require fewer tools on hand
- Built by a trusted connector brand - Simpson straps and plates are recognized across the construction and repair trades for delivering simple, versatile joining solutions backed by consistent manufacturing standards
- Corrosion-resistant for lasting repairs - the G90 galvanized finish is not just a surface treatment; it is a coating level that adds meaningful protection against rust and deterioration, extending the life of the repair in damp or humid conditions
- Purpose-matched for light repair work - rather than using a structural connector where a simpler solution is appropriate, the MP14 is specifically designed for general wood mending tasks, giving buyers the right product for everyday fix-up and joint reinforcement without unnecessary complexity
