The Harger FGA1.5/2-3.5/42WC24 is a fence gate bonding assembly that maintains electrical continuity across a swinging gate. It pairs two tinned copper pipe brackets with a 24 in. #2 AWG welding cable flex jumper: one bracket clamps a gate post of 1.5 in. to 2 in. nominal pipe size, the other clamps a fence post of 3.5 in. to 4 in. nominal pipe size. Because the brackets are compression lug type and clamp mechanically with stainless steel U-bolts, the assembly is used where it is not feasible to exothermically weld to the fence or gate post.
What is included in the FGA1.5/2-3.5/42WC24
- Tinned copper bracket for 1.5 in. to 2 in. nominal pipe (1.9 in. to 2.38 in. actual outside diameter)
- Tinned copper bracket for 3.5 in. to 4 in. nominal pipe (4.0 in. to 4.5 in. actual outside diameter)
- #2 AWG welding cable flex jumper, 24 in. long, factory attached to both brackets
- 5/16 in. stainless steel U-bolts and stainless steel mounting hardware
Approximate weight is 3 lb. Sold as each.
What the FGA1.5/2-3.5/42WC24 fits
The FGA1.5/2-3.5/42WC24 is sized by nominal pipe size, not by measured diameter, so check both columns before ordering. The smaller bracket covers a 1.5 in. to 2 in. nominal gate post, which measures 1.9 in. to 2.38 in. across in the field. The larger bracket covers a 3.5 in. to 4 in. nominal fence post, which measures 4.0 in. to 4.5 in. across.
Choosing between the three Harger fence gate assemblies
Harger builds this family in three standard fence post sizes. All three use the same 1.5 in. to 2 in. gate post bracket and the same #2 AWG, 24 in. jumper, so the only variable is the fence post bracket.
| Part number | Nominal gate post | Nominal fence post | Jumper | Approx. weight |
|---|---|---|---|---|
| FGA1.5/2-2.5/32WC24 | 1.5 in. to 2 in. | 2.5 in. to 3 in. | #2 AWG, 24 in. | 2.5 lb |
| FGA1.5/2-3.5/42WC24 | 1.5 in. to 2 in. | 3.5 in. to 4 in. | #2 AWG, 24 in. | 3 lb |
| FGA1.5/2-5/62WC24 | 1.5 in. to 2 in. | 5 in. to 6 in. | #2 AWG, 24 in. | 3.5 lb |
Harger also offers this family in custom configurations if none of the three standard sizes match your posts.
Where a fence gate assembly is used
A grounded perimeter fence is only continuous while the gate is closed. A gate hangs on hinges, and hinge hardware is not a reliable electrical path, so the gate leaf and the gate post can sit at a different potential from the rest of the bonded fence. A fence gate assembly bridges that break with a flexible jumper that tolerates the gate swinging through its full arc. Harger describes the assembly as an integral component of a fence grounding system that helps eliminate dangerous touch potential.
Fence and gate bonding is routine work at communications sites, substations, solar sites, and any fenced compound with a designed grounding system. The compression lug approach is specified when exothermic welding to the post is impractical, whether that is because of galvanizing, an existing fence you do not own, site restrictions on hot work, or a post wall too thin to weld.

Frequently asked questions
What post sizes does the Harger FGA1.5/2-3.5/42WC24 fit?
It fits a 1.5 in. to 2 in. nominal gate post and a 3.5 in. to 4 in. nominal fence post. In measured terms that is a gate post of 1.9 in. to 2.38 in. actual outside diameter and a fence post of 4.0 in. to 4.5 in. actual outside diameter.
What size jumper does it use?
The FGA1.5/2-3.5/42WC24 uses a 24 in. flex jumper made from #2 AWG welding cable. All three assemblies in the Harger fence gate family use the same #2 AWG, 24 in. jumper.
Do I need to exothermically weld anything to install it?
No. The FGA1.5/2-3.5/42WC24 is the compression lug version of the fence gate assembly, which Harger offers specifically for situations where exothermically welding to the fence or gate post is not feasible. Both brackets clamp mechanically with stainless steel U-bolts.
Which bracket goes on the gate and which goes on the fence?
The smaller bracket, sized for 1.5 in. to 2 in. nominal pipe, is the gate post bracket. The larger bracket, sized for 3.5 in. to 4 in. nominal pipe, is the fence post bracket. Harger publishes the two size ranges separately as "nominal gate post size range" and "nominal fence post size range."
How is FGA1.5/2-3.5/42WC24 different from FGA1.5/2-2.5/32WC24 and FGA1.5/2-5/62WC24?
Only the fence post bracket differs. FGA1.5/2-2.5/32WC24 takes a 2.5 in. to 3 in. nominal fence post, FGA1.5/2-3.5/42WC24 takes a 3.5 in. to 4 in. nominal fence post, and FGA1.5/2-5/62WC24 takes a 5 in. to 6 in. nominal fence post. All three share the 1.5 in. to 2 in. gate post bracket and the #2 AWG, 24 in. jumper.
What does the part number mean?
Reading FGA1.5/2-3.5/42WC24 left to right: FGA is fence gate assembly, 1.5/2 is the nominal gate post range in inches, 3.5/4 is the nominal fence post range in inches, 2WC is #2 welding cable, and 24 is the jumper length in inches. You may see it written without punctuation as FGA1523542WC24 in distributor catalogs.
Can I get a different post size or jumper length?
Harger lists this family as available in standard or custom configurations. If none of the three standard fence post ranges match your posts, contact us with your measured post diameters and required jumper length and we will quote the custom build.
