## Kee-Klamp® Pipe Railing Assembly and Installation

## Instructions for Use

### THE DESIGN OF STRUCTURES WITH FITTINGS

- Fittings are made from galvanized cast iron and are supplied, as standard, with coated and hardened steel grub screws. They are suitable for use in the construction of tubular structures using standard galvanized steel or aluminum pipe.
- When designing structures with vertical and horizontal members which cross within a fitting, tube continuity must be maintained for the vertical, unless there is a specific structural reason to do otherwise.
- Anchors and fixings must be specified to take account of the fixture thickness and design loads according to the manufacturer’s recommendations.
- Attention must be paid to the nature, mechanical properties and condition of the civil structure or substrate to which the structure is to be fixed to ensure its ability to withstand the design loads.
- Consideration must be given to the environmental conditions (eg: saline, cyclical loads or vibration), which the structure will have to endure in service, and the possible implications for service life and the need for regular inspections to check the integrity and condition of structures and the tightness of grub screws.
- Fittings must not be used in scaffolding.
- Fittings must not be welded.
- Contact Wagner with additional questions.

### GENERAL INSTRUCTIONS FOR THE USE OF FITTINGS

- All set screws must be tightened to 29 ft-lb. Always ensure that the pointed, cutting end of the grub screw is placed against the tube and that the flat end is away from the tube.
- Wherever possible, Fittings should be assembled with the open faces of set screws pointing downwards (or horizontally) to minimize collection and retention of rainwater etc.
- Do not re-use set screws; replace with new set screws from Kee Systems Ltd.
- Do not modify fittings; do not use fittings which are (or appear to be) damaged or defective in any way.
- Do not mix Kee Klamp with other brands, use only genuine Kee Klamp to which these instructions relate exclusively.

### SPECIFIC LIMITATIONS ON THE USE OF FITTINGS

- ‘A’ pre-fix add-on types — ensure tapered pins are inserted through both sets of lugs and tapped securely into place before tightening the grub screws.
- Swivels — Types KK19, KK50 — must not be used to support bending loads; entire structures must not be constructed from swivel Fittings for reasons of stability.
- Types KK 14 and KK 18 Must not be used to join top and mid rails within the same bay, not more than one joint is allowed between structural supports.
- The hex head bolt is for retaining purposes only and must be torqued up to 11 ft-lb.
- Type KK18 Must not be used for structural joints or to take a tensile load.
- Types KK58, KK60 and KK61 Must not be used as base flanges to support guard railing or balustrades
- Types KK62 and KK67 must be used with fixing holes orientated in line with the applied load for maximum resistance.
- Type KK63 is only suitable for lightly loaded applications; otherwise, use KKtype 62 with a cranked upright.
- Types KK68 and KK115, when used with spacers, maximum fixture thickness must be in accordance with the fixing manufacturer’s recommendations.
- Type KK70 Must not be used as a side-fix balustrade flange; use typeKK64, KK68 or KK115.
- Type KK72 If used in a permanent or high load application, the type KK72 must be drilled and pinned to prevent rotation on the tube.
- Types KK78 and KK83 When used as top and bottom pairs in gate hinges, the pins must be orientated in opposite directions to ensure gate retention.
- Types KK81 and KK82 Must be used with the retention clips as supplied.
- Joining of tubes within Fittings Tubes must not be joined within any barrel having only one grub screw unless first secured with a type KK18 splice.
- De-burring of cut tubes In order to avoid the danger of cuts or snagging, cut ends must be de-burred, especially when used with types KK18, KK77 or KK84.

### TRANSPORTATION AND STORAGE

- There are no particular limitations as to transportation and storage of Fittings other than they should be kept in a dry and ventilated environment.

## Guardrail Assembly

### Straight and Level Guard Rail

#### Using Types KK10, KK15, KK20, KK21, KK25, & KK26

Where:

L = distance between centers of posts

I = length of the horizontal pipe

H = distance from the ground to the center line of the top rail

h = length of post

Table 1: Dimension ‘x’ for fittings shown above, including Types 35, 40 and L35*

Fitting Size | x |

1″ Pipe (1.315″ Diameter) | –.67″ |

1-1/4″ Pipe (1.66″ Diameter) | –.87″ |

1-1/2″ Pipe (1.90″ Diameter) | –.98″ |

2″ Pipe (2.375″ Diameter) | –1.18″ |

**Note:** When reducing fittings are being used care must be taken to use the correct ‘x’ dimension. (i.e., Type KK10-87, 1-1/2″ Pipe Post with 1-1/4″ horizontal pipe rail. To find the correct length of the horizontal tube, the length ‘x’ is that for the size 1-1/2″ Pipe Post vertical tube.)

When using Types KK35 and KK40 the above ‘x’ dimension should be used.

### Guardrailing up Slopes 0°–11°

#### Using Fitting Types KK86, KK87, KK88 and KK89

Where the upright remains vertical, i.e. ramps and stairways,

(i) dimension ‘x’ to be subtracted from the post dimension measured on the slope to give rail length. (I = L – 2x);

(ii) dimension ‘y’ to be added to the center dimension to give the length of the upright (H = h + y + ground fixing).

Table 2 gives details of dimensions required for calculating the rail lengths, where angles are between 0° and 11°.
