These non-elastic, nylon rear window roll up strap loops have been designed so they will install on all Jeep Wrangler Soft Top frames, from 1997 thru 2018, both 4 Door and 2 Door models.
Not f9r the 2019 JL models.

 
We use a YKK side release buckle to secure the rolled up rear window so it is positioned high and gives an unobstructed rear mirror view. Instructions are included and no tools (See note 1) are required to install the deluxe style loop straps.

(Note 1 - Scissors for earlier 1997 thru 2002 models to cut off old straps)
