Kong stainless steel swivel anchor connector Facts and Features:
- Ideal for reducing chain twist when trying to bring an anchor to the surface
- Allows the anchor to swivel independently and the connector to ride smoothly over the bow roller
- Designed to go over bow rollers and pass through hawse pipes without snagging
- Manufactured by Kong from polished 316 marine grade stainless steel
- Kong rated break load for assurance
N.B. It is advisable to fit a suitable bow shackle between the anchor shank and the connector to reduce lateral load risk - this is explained in the diagram below.
This picture shows a connector fitted with one bow shackle:
Please note that the smaller end of the swivel is designed to connect to your anchor chain
A Maillon Rapide/ fixed connector could also be used to connect to the anchor.
There is a popular solution for preventing potential lateral load failure by enabling articulation.
Fit an additional 3 links of anchor chain between the shackle (or other fixed connection) and the swivel connector.
3 links of Anchor Chain or 3 links of S/S Anchor Chain
The 3 links make the connection between the anchor end of the swivel and the shackle on the anchor.
The swivel connector is connected to the anchor chain.
For KGAC08-S: 6-8mm connector (BRS-77.318.106) - use 3 links of 10mm chain
For KGAC10-S: 8-12mm connector (BRS-77.318.108) - use 3 links of 12mm chain
The picture below shows the correct configuration with one bow shackle and 3 links of connecting chain:
If the hole/cutout in the anchor shank has sharp edges and will not accept the crown of the bow shackle in a proper load bearing manner, it may be pertinent to fit two shackles back to back.
The picture below shows this optional configuration with an extra D shackle:
The diagram below is the Kong illustration of the need to avoid a direct lateral (side) load:
|Kong Number||Kong Chain Size||Jaw Width on Anchor End||Kong Break Load Straight||Kong Safe Working Load Lateral||Compatibility|
Kong Chain Size = the chain sizes that fit on the chain end, not the anchor end
MBL = Manufacturer (Kong) straight Break Load
MWL = Manufacturer (Kong) lateral Safe Working Load
Compatibility = reasonable compatibility with Grade 40 chain break load
For those with narrow bow roller channels, we have estimated the width required for the swivel to pass through unhindered:
|Kong Swivel||Clearance required**|
** because of the profile, the clearance required for the swivel to pass through a narrow channel is estimated as greater than the dimension B in the table above.
Kong Swivel Assembly/Disassembly Illustration
The Kong swivel anchor connector can be disassembled to attach the chain and either chain or the anchor.
