Reverse loops on DC or DCC (the loop and the mainline must be insulated so an auto-reverser can flip polarity). DCC layouts that segment power districts for short protection. Frog feeders on powered-frog turnouts where you don't want the frog to feed-through to the next rail. Bridging into a turntable approach where the turntable rail polarity is independent. Whenever you cut a power district, two insulated joiners (one per rail) cleanly mark the boundary.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDrop-in.\u003c\/strong\u003e Same dimensions as Atlas standard metal rail joiners, identical fit to all Atlas Code 83 Snap Track, Custom Line, and Code 83 flex track. 24 per pack covers 12 complete two-rail breaks — enough for a small layout or one DCC reverse loop module.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale:\u003c\/strong\u003e HO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail Code:\u003c\/strong\u003e Code 83\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Insulated rail joiner (plastic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePieces per Pack:\u003c\/strong\u003e 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Atlas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU \/ Item Number:\u003c\/strong\u003e 552\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 553\u003c\/strong\u003e — Code 83 terminal rail joiners (1 pair), feeders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 554\u003c\/strong\u003e — Code 83 9\" straight terminal track with wire (1 pair)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 520–525\u003c\/strong\u003e — Code 83 straights and fillers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 530–537\u003c\/strong\u003e — Code 83 curve sections\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Atlas","offers":[{"title":"Default Title","offer_id":45097019408566,"sku":"150-552","price":4.04,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/5131\/1286\/files\/57_c9ccae4c-5a8d-435e-a7b8-fd6fdcd4aacc.jpg?v=1777515297","url":"https:\/\/oakvillemodeltrains.com\/products\/atlas-552-ho-scale-code-83-insulated-rail-joiners-24pcs","provider":"Oakville Model Trains Depot","version":"1.0","type":"link"}
