it isnt as locked in as say a wide twinnie strap, but then i never had my straps tight on my surfboard.
it comes with wedges so you can angle them down for a tighter feel if desired.
i am going to just use these and leave them loose as that is the way i like it (wait a minute, thats norty

)
i have photos but i cant get them under 200 to put on the site.
PM me if you want me to email em to ya.
