Kee Klamp Crossovers
Kee Klamp® crossovers carry one pipe run past another where rails intersect but must not be joined in line — unlike a cross or tee, which connects the pipes. Choose the Type 17 clamp-on crossover, 45 crossover, A45 split crossover, 46 combination socket tee/crossover, or 121 corner crossover to route tubing cleanly around obstructions. Each malleable-iron fitting (ASTM A47) slides onto plain-end Schedule 40 pipe and locks with a case-hardened hex set screw — no welding, threading, or special tools. Every fitting is hot-dip galvanized to ASTM A123 for lasting corrosion resistance.
No-Weld, Slip-On Assembly
Kee Klamp crossovers 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
Crossovers 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 does a crossover fitting do?
A crossover carries one length of pipe past another where two runs cross but must not be joined in line. Unlike a cross or tee — which physically joins the pipes at the intersection — a crossover keeps the passing run continuous and offset, so rails can overlap without connecting.
2. Which pipe sizes do these crossovers fit?
The size is the last digit of the part number. Size 5 fits 3/4" pipe, 6 fits 1", 7 fits 1-1/4", 8 fits 1-1/2", and 9 fits 2" pipe. Note that size 8 is 1-1/2" and size 9 is 2". Sizes 6, 7, 8, and 9 are the common railing sizes.
3. Do I need to weld these fittings?
No. Kee Klamp crossovers are slip-on and weldless. The fitting slides onto plain-end Schedule 40 pipe and locks with a case-hardened hex (Allen) set screw tightened with a ratchet wrench. There is no welding, no threading, and no special tooling required to build or reconfigure a run on site.
4. How strong are the set-screw connections?
In Kee sizes 5–9, each set screw supports a 2,000 lb (907 kg) axial load when tightened to 29 ft-lb (39.3 N-m), with a 2:1 safety factor. Load capacity is a property of the assembled, correctly installed system — not a single fitting — and depends on pipe, anchoring, and geometry.
5. Can a crossover help meet OSHA guardrail requirements?
Kee Klamp is a component system used to build guardrail that can meet OSHA 29 CFR 1910.29 and 1926.502. When sizes 7, 8, or 9 build a 42" rail with correct pipe and installation, the assembled system can meet the 200 lb top-rail design load — subject to correct pipe, anchoring, and post spacing.
6. Are these crossovers suitable for outdoor use?
Yes. Crossovers are malleable iron castings to ASTM A47 (grade 32510), hot-dip galvanized to ASTM A123 for indoor and outdoor corrosion resistance. They pair with standard Schedule 40 steel pipe to ASTM A53. Aluminum (Kee Lite) and Kee Koat powder-coat options are also available.
