RaceQuip's all 2" small buckle Latch & Link Pro 5-point auto racing harness set has twin individual HANS / HNR style shoulder belts and is manufactured using premium polyester webbing and drop forged steel black hardware to exceed the SFI 16.1 rating. Shoulders are 2" width to accommodate a HANS or other Head & Neck Restraint Device and adjust from 26" to 62" in length. The 2" wide lap belt adjusts from 30" to 65". Many racers now prefer a 2" lap belt because it tucks under the iliac crest (hip bone) so that you can get the lap belt tighter. This harness set is a "pull up lap" design, which means that the lap belt straps must be pulled up and toward the center latch & link buckle mechanism to tighten the belts. This 2" Pro Harness set features a small compact design buckle that is lightweight and stays out of the way. Both shoulder belts and the sub-belt are hooked over the link; the link is inserted into the latch on the lap belt; the lever is then brought down into and over the link, securely holding all the pieces in place. Since RaceQuip seat belt sets are "double adjustable", lengths are simply adjusted on either end for ease of installation. Using the included three bar slide you can mount the belts by either wrapping them around a rollbar or by bolting them in place.
