The RPC Clip - Technical and Physical Attributes
A. General Attributes
The RAPID POSITIONING CLIP is a unique one-piece design manufactured from a composite polyamide alloy combining strength with light weight.
The RAPID POSITIONING CLIP is designed to be extremely quick and simple to use. It is designed to support and locate a number of piping products on a variety of mounting channels, mounted either horizontally or vertically, whilst allowing some expansion movement of the pipe. It is not a structural type of fixing and, although it has a firm hold, it does not tighten down on the channel or pipe work
The RAPID POSITIONING CLIP is designed to fit into all pre-formed channels of a profile width of 41mm with an inturned channel lip of 10mm width and 7mm depth. To ensure there is sufficient grip, allowing for the channel lip tolerances, the feet may prove tight to fit on certain types of mounting channel. To overcome this, a short length of the appropriate sized pipe may be inserted into the clip (with no need to lock over the top) and used to twist the clip into position.
The RAPID POSITIONING CLIP, being a one piece moulding, is a major time saver in the installation of air conditioning and refrigeration pipe-work compared with competing products which are made up of several components. It will help reduce the problems occasioned by cracked and fractured joints.

C. Physical Pull and Slip Tests
A number of pull and slip tests were carried out on the RAPID POSITIONING CLIP under supervision at the Unistrut laboratory in Bedford, England. These tests were performed to give a general indication of the forces necessary to pull the RAPID POSITIONING CLIP out of the channel or to cause slippage along the channel. They were witnessed by ERA Technology Limited, world-wide research, development and testing specialists and a copy of their report is available on written request.
The pull and slip tests were all carried out on Unistrut P2000PG (pre-galvanised) plain channel. Being a smoother channel than the hot dip galvanised, the slip tests were conducted under "worst case scenario" conditions. The tests were undertaken on all sizes of the RAPID POSITIONING CLIP from 3/8" to 1-1/8" diameter. All tests were performed with clips randomly selected from standard production runs and at an ambient temperature of 24° C.
The perpendicular pull tests, to demonstrate the horizontal weight holding capacity of the RAPID POSITIONING CLIP, give results between 80 Kg and 107 Kg. This is a multiple of the weight the clip would be required to hold under normal operating conditions.
The slip tests to show movements along the channel, and to demonstrate the vertical weight holding capacity of the RAPID POSITIONING CLIP, gave results between 7 Kg and 15 Kg, again well in excess of the requirements under normal operating conditions.
It should be emphasised
that these results are only applicable to the RAPID POSITIONING CLIP as
mounted in Unistrut P2000PG channel. Although other manufacturers' channel
may claim to be similar in physical nature and tolerances, there is no
guarantee of equality of aspects, and thus the results may vary.
