Is a special attachment required to connect the last FLEAT rail section to the beginning of the run of guardrail where the straight flare begins?
• No. The contractor must install the FLEAT beginning at the downstream end where the run of guardrail begins and work toward post #1. The splice of the last FLEAT rail section where the flare departure begins (FLEAT post #7 for the 37′-6″ long Test Level 3 system) must be firmly bolted before the rail within the FLEAT itself is flared. If desired, post #7 can be set back a short distance to minimize the severity of the bend at that post. The angle of departure will depend on the offset selected. Based on a Test Level 3 FLEAT that is 37′-6″ long, the maximum angle will be 6.1 degrees for a 4′-0″ offset and the minimum angle will be 3.8 degrees for a 2′-6″ offset. For a Test Level 2 FLEAT, the angle will remain the same but the offset will change to 2′-8″ and 1′-8″ respectively.
