Product Overview
Are you building your own heavy-duty commercial hoop house or upgrading a structural DIY high tunnel? Creating a wind-resistant and snow-tolerant framing system demands dependable hardware connections. Our commercial-grade 1.66″ x 1.375″ Galvanized Steel Greenhouse Cross Connectors are the ultimate purlin brackets designed to anchor your overhead infrastructure. These high-strength steel crossover clamps firmly latch together two perpendicular pieces of pipe, providing a rock-solid structural joint that keeps your framing square and stable under extreme environmental loads.
Forget the tedious hassle of manual drilling, measuring, and individual bolting. This structural greenhouse purlin bracket makes assembly incredibly straightforward, which is an absolute game-changer during difficult overhead rail installations. Ideally sized to bridge a 1.66″ outer diameter arched bow hoop with a 1.375″ horizontal purlin pipe, these brackets provide a flush, heavy-duty grip that connects ridge poles, stabilizer rails, greenhouse arches, or even custom steel propagation tables with ease.
Key Features
- No-Drill Framework Assembly: Completely eliminates the need for drilling holes or structural bolting, preserving the factory strength of your tubing and slashing overhead pipe assembly times.
- Commercial Galvanized Steel: Forged from high-grade galvanized steel to provide maximum resistance against rust, corrosion, and chemical treatments in high-humidity greenhouse environments.
- Complete Clamping Assembly: Each single pack contains a matching set of two interlocking cross-connector halves, supplying everything needed to lock down one perpendicular intersection joint.
- Engineered Dual-Size Fit: Precision-molded to clamp a 1.66″ main pipe (arched hoop) together with a 1.375″ cross pipe (top rail fence conduit or horizontal purlin).
- Versatile Structural Applications: The go-to industrial hardware for bridging ridge lines, aligning ground purlins to bows, or fabricating stable steel workbenches and shelving units.

Frequently Asked Questions (FAQ)
Q1: Why is this connector listed as 1.66″ x 1.375″?
A: This specialized dual-size cross connector is engineered for commercial greenhouse framing. The larger side fits perfectly around a 1.66″ outer diameter structural pipe (typically used for the main arched bows or hoops), while the perpendicular clamp side holds a 1.375″ (1 3/8″) pipe, which is the standard size for horizontal purlins and chain-link fence top rails.
Q2: How many connector pieces do I get in one pack?
A: Each pack includes two (2) cross-connector halves. When placed together around your intersecting pipes, these two pieces interlock and wrap tightly around the junction to fully lock down one (1) single perpendicular joint.
Q3: Do I need to drill holes into my greenhouse hoops to install these brackets?
A: No! The major advantage of using our cross-coupling system is that it completely eliminates the need for drilling or bolting through your pipes. They clamp together firmly from the outside using high-compression friction, preserving the factory structural integrity of your hoops and preventing weak spots where moisture could cause internal rust.
Q4: Can these purlin clamps handle heavy snow and wind loads?
A: Yes. Forged from thick, high-tensile galvanized steel, these brackets act as an industrial brace. They distribute environmental tension evenly across the frame joint, keeping your structural ridge lines and purlins completely rigid under severe weather stress.
