King Block®

Guardrail Offset Block

King Blocks® are injection molded offset blocks composed of 28.7% Ground Recycled Rubber and 70% High Density Polyethylene (HDPE). They are crash tested and meet NCHRP Report 350 Test Level 3 criteria. The King Block may be used as an alternative for wood or steel blocks on W 6×8.5# / 9# (W150x12.6 kg / 13.5kg) steel posts, in 8″ block applications.

Features

  • Self-hanging fingers.
  • Self-aligning side rails.
  • Lightweight – only 4.5 lbs. (2.1 kg)
  • Bottom tab supports rail during installation.
  • Blocks are considered “green” products, environmentally safe and recyclable.
  • Molded product reduces inconsistencies sometimes seen in wood blockouts.
  • Eligible for reimbursement under the Federal-aid Highway program, per FHWA letter HSSD/B-85E, dated May 8th, 2007 as a NCHRP Report 350 Test Level 3 device.

Assembly & Maintenance

  • Self-hanging fingers minimize the need for assistance by end-users during installation.
  • Self-aligning side rails are designed to hold block in place and resist rotation.
  • Narrower width allows easier access to bolts at splices.
  • King blocks retain their original size which reduces the frequency of retightening guardrail
    post bolts.
  • Weather-resistant materials minimize damage related to rain, snow and extreme cold/heat.
  • Formulated with UV inhibitors, to reduce long-term degradation.
  • Blocks are composed of durable materials resulting in less damage by ongoing roadway operations – such as snowplowing and mowing.
