Arris Rail Mortice Repair Bracket – Timber Fence Support & Reinforcement

Restore the structural integrity of your boundary line instantly with our Heavy-Duty Arris Rail Mortice Repair Bracket. Engineered explicitly to fix the most common point of failure in traditional closeboard fencing, this pre-shaped steel bracket repairs a snapped or rotted arris rail right where it slots into the concrete or timber fence post—saving you from purchasing expensive replacement rails or tearing down intact fence panels.

Fabricated from structural carbon steel and finished with a hot-dip galvanized protective layer, this repair shoe mirrors the triangular profile of standard arris rails. It slots tightly over the broken rail end and anchors securely onto the face of the fence post. By reinforcing the weakened joint with high-strength steel, it provides immediate resistance against heavy wind loads and heavy impact, extending the life of your existing fence for a fraction of the cost of a full replacement.

  • Instant Structural Fix: Repairs broken or rotted arris rail joints in minutes, bypassing the need to dismantle or rebuild the fence section.

  • Saves Money and Materials: Reuses your existing, intact timber fence panels by structurally bridging the broken connection point.

  • Precision Triangular Fit: Engineered to slide cleanly onto standard triangular arris rails for a tight, wobble-free reinforcement.

  • Industrial Hot-Dip Galvanized Coating: Zinc-treated to prevent rust and corrosion, even when exposed to trapped moisture inside dark post mortices.

Description

Arris Rail Mortice Repair Bracket – Timber Fence Support & Reinforcement

Overview

Over time, high winds putting pressure on closeboard fence panels place immense stress on the ends of the horizontal arris rails. When the tenon joint inside the post mortice rots or snaps under wind load, the entire fence section sags and loses its structural strength. The Heavy-Duty Arris Rail Mortice Repair Bracket acts as a structural splint, transferring the weight of the fence bay directly back into the post through solid plate steel.

The bracket features a flat flange that mounts flush onto the face of your timber or concrete post, paired with a formed triangular pocket that cradles the arris rail. Thanks to its multi-hole fixing layout, you can easily drive heavy wood screws or masonry anchors through the bracket, clamping the broken timber components back into perfect, rigid alignment.

Key Applications

  • Closeboard Fence Maintenance: Repairing broken horizontal rails on traditional morticed timber or concrete fence posts.

  • Wind Damage Reinforcement: Strengthening weakened or straining arris rail joints before autumn and winter gales arrive.

  • Retrofit Property Upgrades: Securing loose or wobbling fence bays on older properties without replacing full panels.

Contractor Fast Installation & Alignment Tip

Pro Tip: When an arris rail snaps, the heavy fence panel usually sags downward, making the rail end drop below its original line. If you try to screw the repair bracket on while the panel is sagging, your fence line will dry out crooked and out of square.

The Trade Method: Before checking any fixings or placing the bracket, slide a heavy-duty car jack or a sturdy timber lever underneath the bottom gravel board of the sagging fence section. Gently pump or pry the fence panel up until your horizontal arris rail is perfectly level and aligned with its original mortice slot. Hold the panel steady in this elevated position using a temporary prop block, slide the arris rail repair bracket tightly into place over the joint, and drive your screws home. Once secured, remove the jack; the steel bracket will hold the fence perfectly straight and level at its original height.
