It handles up to 7,000 pounds gross towing weight and supports as much as 700 pounds of tongue weight. The unit is intended to mount on a standard straight trailer tongue using 2-1\/2\" x 4-1\/2\" Grade-5 bolts (not included).\u003c\/p\u003e\n\n\u003ch3\u003eHow does this actuator improve trailer braking control?\u003c\/h3\u003e\n\u003cp\u003eThe DA70 translates the trailer's forward inertia into hydraulic pressure for drum brakes, offering smoother, coordinated stopping without an electric brake controller. Its rated capacity supports medium-duty trailers, helping maintain predictable brake response under load. Zinc plating also helps preserve performance by resisting rust on critical moving parts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConverts surge movement into hydraulic brake force for drum systems\u003c\/li\u003e\n  \u003cli\u003e7,000 lb gross towing weight rating for mid-size trailers\u003c\/li\u003e\n  \u003cli\u003eCorrosion-resistant finish for consistent operation over time\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my trailer tongue and coupler requirements?\u003c\/h3\u003e\n\u003cp\u003eThis actuator is built to mount on straight 3\" wide trailer tongues and pairs with a 2\" ball coupler — the industry standard for many utility, equipment, and car hauler trailers. Installation requires two 2-1\/2\" x 4-1\/2\" Grade-5 bolts (sold separately), and the unit is sized to sit flush on common tongue profiles for a straightforward retrofit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMounts on 3\" wide straight trailer tongues\u003c\/li\u003e\n  \u003cli\u003eDesigned for a 2\" ball coupler (EZLatch style)\u003c\/li\u003e\n  \u003cli\u003eUses Grade-5 2-1\/2\" x 4-1\/2\" bolts for secure attachment (not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat features make the EZ-Latch coupler convenient?\u003c\/h3\u003e\n\u003cp\u003eThe EZLatch coupler provides a fast, positive connection to a 2\" tow ball, reducing fumble time and improving repeatable hookups. Its latch geometry simplifies engagement and disengagement while maintaining a secure hold under towing load.

It's a good match for equipment haulers, car trailers, small livestock trailers, and other applications using a straight 3\" tongue and a 2\" ball coupler. If you plan to retrofit or replace an actuator, ensure your tongue dimensions match and budget for Grade-5 mounting bolts during installation.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What towing weight does the DA70 support?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The DA70 is rated for up to 7,000 pounds gross towing weight and 700 pounds maximum tongue weight.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What mounting hardware is required?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Mount the actuator on a 3\" straight tongue using two 2-1\/2\" x 4-1\/2\" Grade-5 bolts, which are not included.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Demco EZ","offers":[{"title":"Default Title","offer_id":48080820535454,"sku":"B0CS3WJZVT","price":243.27,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/demco-ez-da70-front-overview.jpg?v=1785788959","url":"https:\/\/northtrailauto.ca\/products\/demco-ez-da70-surge-brake-actuator-for-hydraulic-drum-brakes-7-000-lb-2-ez-latch-zinc-plated-silver","provider":"North Trail Auto","version":"1.0","type":"link"}
