The easy to install No Tie Aluminum Tru-Peep eliminates the need for serving in your peep and is locked in place by the ingenious crisscross design. Installation is easy and can be done in a matter of minutes. Use a bow press to reduce tension on the bowstring and cables and separate the two strings. Wrap the string along the bottom sidetracks of the peep then through the crisscross pattern before running along the top sidetracks of the peep. Relax the bow press to lock the peep in place and it’s ready to go. This bowhunting peep is constructed of aluminum for supreme strength and durability for years to come. The No Tie Aluminum Tru-Peep is compatible with all compound bows.
