What is in each kit

  • Starter kit: two posts plus one rail (18 in system) or two rails (42 in system)
  • Add-on kit: one post plus one rail (18 in) or two rails (42 in) to extend an existing run
  • Four ½ in Grade 5 bolts, washers and lock washers per rail, with stainless threaded inserts pre-installed in the posts
  • Four ¾ in concrete wedge anchors per post, plus post caps and snap-in button plugs

Rail lengths are measured on post centers. Posts are 4¾ x 4¾ x 3/16 in steel on a 10 x 10 x ½ in footplate; rails are 12 in high, 1/8 in thick and double-ribbed. The system is rated at 12,000 lb at 4 mph. Need just posts? See industrial guardrail posts. Custom rail lengths are available on request. Kits ship from stock.

Protecting the racking itself? See our pallet rack column protectors and end of aisle rack protectors, or browse the rack accessories range.

Frequently asked questions

What is the difference between a starter kit and an add-on kit?

A starter kit has two posts and the rail or rails between them, so it stands on its own. An add-on kit has one post and the rails that reach back to the last post of the run. Buy one starter kit per run, then one add-on kit per additional rail length.

How do I work out how many kits I need?

Divide the run length by the rail length you want (rails are measured on post centers, from 24 to 120 in). The first length is a starter kit and every length after it is an add-on kit. The configuration calculator above does the arithmetic for 8 to 40 ft runs.

Are the floor anchors included?

Yes. Every post ships with four ¾ in concrete wedge anchors, and every rail ships with its four Grade 5 mounting bolts.

Single rail or double rail?

The 18 in single-rail system marks off walkways, machinery and storage zones at knee height. The 42 in double-rail system is the choice wherever forklifts travel: dock doors, in-plant offices, inventory protection zones and rack ends.

Can I turn a corner or add a gap for foot traffic?

Yes. Every post is punched on all four sides, so a corner is just another add-on kit mounted at 90 degrees. Lift-out rail cuffs for a removable section, and custom rail lengths, are available on request.
