AP7920B Loose Connections

[RASB]

Hi

We've purchased some AP7920B units.

All power cables into each socket feel loose. If they 'droop' downwards the power will be lost.

This is alleviated by using cable ties on the retention bracket to force the cable to remain in position but it is not ideal.

We are using LINDY brand IEC cables (C13 to C14). 

I wanted to check if there are APC brand cables which provide a better connection, or any advice on specific cables to use for a more secure connection.

There are some latching APC cables provided for the AP8xxx series (yellow ones) but I can't see anything specific for the AP7xxx series.

Thanks
