Border lacing connects the main fishing net panel to the border rope.
It may look like a small assembly detail, but it has an important structural role.
If the lacing is too tight, the main mesh may be pulled unnaturally toward the border.
If it is too loose, the border and main panel may not share load consistently.
The key principle is:
Good border lacing should connect the panel and border evenly without creating excessive gathering or uncontrolled slack.
Over-tight lacing often pulls the edge meshes inward.
Typical signs include:
Compressed edge meshes
Strong gathering near the border
Wavy panel surface
Tight corners
Diagonal wrinkles extending inward
The border may look very straight while the nearby mesh appears distorted.
A useful inspection method is to compare:
Center mesh
Mid-edge mesh
Corner mesh
If the edge meshes are much smaller or more compressed than the center meshes, excessive lacing tension may be involved.
The difference should be judged under the same panel condition.
Border lacing should distribute the main net reasonably evenly.
If several meshes are pulled into one short lacing section, the edge may appear bunched.
Warning signs include:
Clusters of compressed meshes
Uneven spacing
Repeated folds
Local hard spots
These can indicate that too much mesh has been gathered into too little border length.
Loose lacing creates a different pattern.
Look for:
Large gaps between mesh and border
Excess movement between components
Uneven edge position
Sagging lacing sections
Border movement independent of the main panel
The main mesh may not follow the border consistently when light tension is applied.
Inspect the finished panel under light, controlled tension.
Do not pull the net aggressively.
Observe whether:
Border and mesh move together
Lacing becomes extremely tight immediately
Large slack loops remain
One section loads much earlier than neighboring sections
This can reveal uneven load sharing.
Check whether the distance between lacing points is reasonably consistent.
Irregular spacing may create:
Tight zones
Loose zones
Uneven edge geometry
A single abnormal section may pull differently even when the rest of the border looks correct.
Corners often behave differently from straight borders.
They may contain:
Extra reinforcement
More concentrated lacing
Attachment loops
Multiple border directions
Inspect whether the corner lacing is significantly tighter than the adjacent straight sections.
Over-tight corners can pull the entire panel out of square.
Excessive lacing tension can rotate nearby diamond meshes.
You may see:
Meshes becoming narrow near the border
Mesh diagonals changing direction
Gradual transition from distorted edge mesh to normal center mesh
This can be a useful sign of local over-tension.
Sometimes the lacing looks too tight because the border rope itself is too short.
Likewise, loose-looking lacing may occur because the border is too long.
Therefore, check:
Border effective length
Main panel dimensions
Lacing spacing
Edge mesh geometry
before blaming the lacing alone.
Opposite borders provide a useful reference.
If one side shows:
Strong gathering
Smaller edge meshes
Harder lacing
while the opposite side remains relaxed, the assembly may be uneven.
This is especially important for rectangular fish cage panels.
Check for excessive tightness:
Compressed edge meshes
Strong gathering
Tight corners
Diagonal wrinkles
Border becomes loaded before nearby mesh
Check for excessive looseness:
Large slack loops
Gaps between border and mesh
Excessive relative movement
Uneven edge alignment
Some lacing points remain unloaded
Also compare:
Lacing spacing
Opposite borders
Corner condition
Border length
Panel diagonals
Border lacing helps transfer force between:
Main Mesh → Border Rope → Attachment System
If the lacing is uneven, load may bypass some areas and concentrate in others.
That can contribute to:
Edge distortion
Local mesh overload
Corner stress
Difficult installation
Uneven attachment loading
The goal is not to make border lacing as tight as possible.
It should be tight enough to control the relationship between the border and main net, but not so tight that it forces the panel into an unnatural shape.
The key principle is:
Too-Tight Lacing Creates Gathering and Local Preload, While Too-Loose Lacing Creates Poor Load Transfer and Excess Movement.
A stronger inspection combines:
Lacing Spacing + Edge Mesh Shape + Border Length + Corner Condition + Controlled Tension + Opposite-Side Comparison
