Product Overview
Are you building your own commercial hoop house or DIY backyard greenhouse? Creating a rugged, wind-resistant structural frame demands dependable hardware connections. Our commercial-grade 1 3/8″ x 1 3/8″ Galvanized Steel Greenhouse Cross Connectors are the ultimate purlin brackets designed to secure your structural infrastructure. These high-strength steel clamps firmly latch together two perpendicular pieces of pipe, providing a rock-solid joint that keeps your high tunnel square and stable under heavy wind and snow loads.
Forget the hassle of manual drilling, measuring, and individual bolting. This structural greenhouse purlin bracket makes assembly incredibly straightforward, which is especially vital during tedious overhead rail installations. Ideally sized to wrap around standard 1 3/8″ top rail fence piping, these crossover clamps provide a flush, heavy-duty grip that connects ridge poles, horizontal purlins, greenhouse bows, and even custom steel support tables with ease.
Key Features
- No-Drill Installation: Eliminates the need for drilling holes or structural bolting, dramatically speeding up overhead pipe assembly times.
- Commercial Galvanized Steel: Forged from high-grade galvanized steel to provide maximum rust, corrosion, and chemical resistance in high-humidity greenhouse environments.
- Complete Clamping Set: Each single pack contains a matching set of two interlocking cross-connector pieces, supplying everything needed to secure one intersection joint.
- Universal 1 3/8″ Pipe Fit: Precision-sized to clamp 1 3/8″ x 1 3/8″ perpendicular configurations, making them completely compatible with standard 1 3/8″ top rail fence conduits.
- Versatile Structural Applications: The go-to hardware for bridging ridge lines, aligning ground purlins to bows, or fabricating stable steel workbenches.

Frequently Asked Questions (FAQ)
Q1: How many connectors do I receive in one pack?
A: Each pack includes a set of two (2) cross-connector halves. Together, these two pieces interlock around your intersecting pipes to fully lock down one (1) single perpendicular joint.
Q2: What size pipe are these purlin brackets designed to clamp?
A: These cross brackets are precision-engineered to fit standard 1 3/8″ outer diameter (OD) piping. This matches standard 1 3/8″ top rail chain-link fence tubing, which is widely available and popular for DIY greenhouse hoops.
Q3: Do I need to drill holes into my greenhouse bows to install these?
A: No! The best advantage of using these connectors is that they completely eliminate the need for drilling or bolting through your structural pipes. They clamp together firmly from the outside, which preserves the structural integrity of your hoops and prevents weak spots where rust or bending could occur.
Q4: Can these be used to build things other than greenhouse roofs?
A: Absolutely. While they are primarily used to secure ridge poles and purlins to greenhouse bows overhead, commercial farmers also use these 1 3/8″ galvanized clamps to build custom steel plant support tables, shade structures, or netting enclosures.
