Conteg Patch Panel Keystone Adapter

This is an adapter to fit a Keystone module into a Conteg DP-PP-S1U patch panel. This patch panel is sold in shops, being labeled as "type Keystone", but it doesn't actually fit Keystones, requiring additional adapters called Conteg DP-KEY. This is a replacement for those adapters, as I'm surely not going to the effort and expense of getting those. >:(

Also included is a model for a simple blank-off piece to fill any unused holes.
