Kee Klamp Plugs
Kee Klamp plugs cap the open end of a pipe for a safe, finished appearance and to keep out debris and moisture. The Type 84 plug is a malleable iron casting — produced to ASTM A47 and hot-dip galvanized to ASTM A123 — that locks onto the pipe with a case-hardened hex (Allen) set screw. The Type 77 plug is a plastic push-in fitting. Both close exposed tube ends across the eight Kee Klamp pipe sizes, covering pipe from 1/4" up to 2".
No-Weld, Slip-On Assembly
Kee Klamp plugs 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
Plugs 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 is a Kee Klamp plug used for?
A plug caps the open end of a pipe or tube so the framework has a safe, finished appearance instead of a sharp, exposed rim. Closing the end also keeps debris and moisture out of the pipe. Plugs are a simple finishing detail on handrails, guardrails, and other Kee Klamp structures.
2. What is the difference between the Type 84 and Type 77 plug?
The Type 84 is a malleable iron (galvanized metal) plug that is secured to the pipe with a hex set screw. The Type 77 is a plastic push-in plug that presses into the pipe end. Choose the Type 84 for a metal fitting fixed with a screw, or the Type 77 for a quick plastic insert.
3. What are Kee Klamp plugs made from?
The Type 84 metal plug is a malleable iron casting produced to ASTM A47 (grade 32510) and hot-dip galvanized to ASTM A123 for indoor and outdoor corrosion resistance. The Type 77 plug is molded plastic. Materials match the rest of the Kee Klamp slip-on fitting system.
4. How does the Type 84 plug attach to the pipe?
Like most Kee Klamp fittings, the Type 84 plug slides onto plain-end pipe and locks with a case-hardened hex (Allen) set screw — no welding, threading, or special tools. Set screws are tightened with a ratchet wrench. The Type 77 plastic plug simply pushes in and needs no set screw.
5. What pipe sizes do Kee Klamp plugs fit?
Kee Klamp is built in eight pipe sizes (component sizes 2–9), and the size is the last digit of the part number. Common sizes are 5 = 3/4", 6 = 1", 7 = 1-1/4", 8 = 1-1/2", and 9 = 2". Match the plug size to the pipe you are capping.
6. Do I need special tools to install a plug?
No. The Type 84 metal plug installs with a standard hex (Allen) key or a ratchet wrench to set the screw — there is no welding or threading. The Type 77 plastic plug pushes in by hand. Both are part of the weldless, slip-on Kee Klamp system.
