Kee Klamp Flanges
Kee Klamp® flanges terminate or mount pipe to a flat surface and finish exposed ends. This range spans the Type 61 flange, Type 60 extra-heavy and high-capacity Type 623 railing flanges, the Type 118 cover flange, Type 59 spigot flange, Type 31 pallet flange, C58 swivel flange, and Type 70 rail support. 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 — and is hot-dip galvanized to ASTM A123. Standard floor and wall base flanges live in the Bases category.
No-Weld, Slip-On Assembly
Kee Klamp flanges 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
Flanges 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 Kee Klamp flange do?
A flange anchors or terminates a pipe against a flat surface, or covers an exposed pipe end for a finished appearance. Depending on the type, it can start an upright, cap a rail run, or provide a mounting point on a wall or structural surface. The pipe slips in and is secured with a case-hardened hex set screw.
2. How do the standard, heavy-duty, and cover flanges differ?
The Type 61 is the standard railing flange for general uprights. The Type 60 extra-heavy and high-capacity Type 623 railing flanges use a more robust casting for demanding mounting situations. The Type 118 cover flange conceals a base or pipe end for a clean, finished look rather than carrying primary structural duty.
3. What are the spigot, swivel, and rail-support flanges for?
The Type 59 spigot flange presents a spigot that inserts into a pipe end to mount it to a surface. The C58 swivel flange angles the mounting, the Type 31 pallet flange suits pallet-rack fixing, and the Type 70 rail support carries a passing rail — each addressing a specialized mounting need within this range.
4. Which pipe sizes do these flanges 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. Size 8 is 1-1/2" and size 9 is 2" — a 61-9, for example, fits 2" pipe. Sizes 6, 7, 8, and 9 are the common railing sizes.
5. Do these flanges require welding to install?
No. Each flange slips onto plain-end Schedule 40 steel pipe and locks with a case-hardened hex (Allen) set screw tightened with a ratchet wrench, so no welding, threading, or special tools are needed. Mounting holes let you fasten the flange to concrete, steel, or timber with anchors suited to the substrate (sold separately).
6. How strong are these flanges, and can they meet OSHA?
In Kee sizes 5–9, each set screw supports a 2,000 lb (907 kg) axial load at 29 ft-lb (39.3 N-m), with a 2:1 safety factor. When sizes 7, 8, or 9 build a 42" rail with correct pipe and installation, the assembled system can meet OSHA's 200 lb top-rail load — a property of the installed system, not any single flange.
