QuickPop installation is very simple.
Once you have attached the strap to your lower bracket the hook can be pushed over the top bracket.
The first few times the hook is popped on will be very tight, this is normal and will 'bed in' over time.
Watch the installation video for the optimal technique.
When you are happy with the QuickPops the strap can be cut down to length.
Bear in mind, too long of a strap will look untidy. Too short of a strap will be harder to pull tight.
The ideal length would be 10-15cm. Enough to grip with two fingers and a thumb.
