Dramm - Jack Chain
Brand: Dramm
Jack Chain
This is jack chain supplied by the roll for hanging work in the greenhouse. Dramm stocks it in one size and one length: No. 14 chain, 100 ft to a roll. It is the chain growers use to drop irrigation lines, bench and basket rail and hanging baskets off the house structure, cut to length on the bench and opened and closed link by link with two pairs of pliers. Dramm publishes no material, finish or load rating for the item, so the trade size and the roll length are the only figures given here.
There is one size and one length on this page: No. 14 chain on a 100 ft roll, so the only decision is how many rolls. Because Dramm publishes no working load for it, treat it as suspension chain for irrigation line, rail and basket drops and hang anything heavy from cable or strap instead. Buying it on the roll is the point of the item: cut each drop to the length that bay needs, then open and close the end links with two pairs of pliers rather than adding connectors or hooks. If the run is PolyRail rather than baskets, the rail carries its own top hangers and connecting bands and the chain is simply what those hang from.

Key Features
- No. 14 jack chain, the single size Dramm stocks for greenhouse hanging work.
- Supplied on a 100 ft roll, so each drop is cut to the length the bay actually needs.
- Links open and close with two pairs of pliers, so a drop can be shortened, joined or re-hung without connectors.
- Used for irrigation line, bench and basket rail and hanging baskets off the house structure.
- Dramm publishes no load rating for it, so it is specified here as suspension chain rather than lifting chain.
