Kee Klamp Crosses
Kee Klamp® crosses join intersecting rails and mid-rails without welding. The range includes the Type 26 two-socket and Type 35 three-socket crosses, the four-socket Type 40, the adjustable Type 30 (30–45°), and the Type 89 angle cross—plus split A26, A35, and A40 versions that open to fit onto pipe already in place. Each socket grips plain-end Schedule 40 pipe and locks with a case-hardened hex set screw, so intersecting frames go together with no threading and no special tools.
No-Weld, Slip-On Assembly
Kee Klamp crosses are part of a slip-fit pipe system: components connect to plain-end Schedule 40 pipe and lock with a case-hardened hex (Allen) set screw—no welding, threading, or hot-work permits. Tighten to spec with a ratchet wrench and the joint is ready to carry load, so a railing or frame can be built, adjusted, or extended on site with basic hand tools.
OSHA-Ready & Corrosion-Resistant
Crosses are malleable iron cast to ASTM A47 (grade 32510) and hot-dip galvanized to ASTM A123 for indoor or outdoor service. Kee Klamp is a component system: built into a 42" guardrail with the correct pipe, anchoring, and post spacing, sizes 7, 8, and 9 help the assembled system meet OSHA 29 CFR 1910.29 and 1926.502 design loads—compliance is a property of the installed railing, not any single fitting.
FAQs
1. What are Kee Klamp crosses used for?
Crosses connect rails and mid-rails where they intersect. The Type 26 provides two sockets, the Type 35 three, and the Type 40 four. The adjustable Type 30 handles 30–45° intersections and the Type 89 angle cross joins rails at an angle—useful for mid-rails, braces, and infill framework.
2. What is a "split" cross (A26, A35, A40)?
Split crosses—the A26, A35, and A40—open along a separating half so they can be fitted onto pipe that is already installed, without dismantling the run. Standard 26, 35, and 40 crosses are sockets that pipe passes into or seats within, ideal when you build the frame from loose lengths.
3. What pipe sizes do Kee Klamp crosses fit?
Crosses fit standard Schedule 40 pipe in eight sizes from 1/4" to 2" (component sizes 2–9); the size is the last digit of the part number. Common railing sizes are 6 (1"), 7 (1-1/4"), 8 (1-1/2"), and 9 (2"). Remember size 8 is 1-1/2" and size 9 is 2".
4. Do I need to weld the intersection?
No. Crosses are slip-on, weldless fittings. Sockets slide onto plain-end pipe and lock with a case-hardened hex (Allen) set screw tightened with a ratchet wrench—no welding, threading, or special tools. Split versions clamp onto pipe already in place, so you can add a mid-rail or cross without cutting the existing run.
5. How strong is a cross joint, and can it help meet OSHA?
Each set screw supports a 2,000 lb (907 kg) axial load at 29 ft-lb with a 2:1 safety factor. Because Kee Klamp is a component system, a cross joint’s strength depends on the whole assembly. Using sizes 7, 8, or 9 in a correctly built and anchored 42" guardrail, the system can meet OSHA 29 CFR 1910.29 and 1926.502 design loads.
6. What are Kee Klamp crosses made of?
Kee Klamp fittings are malleable iron castings to ASTM A47 (grade 32510), hot-dip galvanized to ASTM A123 for indoor and outdoor corrosion resistance. They are designed for standard Schedule 40 steel pipe to ASTM A53. Aluminum (Kee Lite) and Kee Koat powder-coat options are also available.
