90 deg Aluminum Cam Block (Pair)
Heavy Duty Aluminum Upgrade Cam Blocks for #620, #622 & #622-5 Retracts.
(Please Note: These aluminum cam blocks replace the original plastic cam blocks. The plastic cam blocks were designed to fail under severe load conditions to prevent the retracts from breaking out of the wing or causing damage to the retract unit itself. The aluminum blocks will not provide this feature.) (Use at your own risk)
