Title of Treatment: Hang Sash with Chain

Class of Treatment: [ ] Maintain, [ ] Stabilize, [x] Repair, [ ] Upgrade, [ ] Exception
Type of Treatment: [x] Traditional, [ ] Modern

Condition to be treated: Sashes run in tracks smoothly and fit the opening. Sashes ready to be hung on chains.

Description: Hang two double-hung sash with metal chain and adjust for smooth operation.

Typical Procedure:

1. Weigh sashes and weighs, and assure they match. Be sure the sash pulley wheels are wide enough and shaped correctly for the chain to roll freely.
2. Determine the length of chain needed by measuring the full height of the window opening. This measurement will be the length to cut the chain.
3. Cut the chain with side cutters, end cutters or a small bolt cutter.
4. Hang the upper sash first. Run a chain through the pulley. Insert a nail into a link, or attach a small spring clamp to keep the end of the chain from falling through the pulley.
5. Attach the chain to the weight. Put the end of the chain through the hole at the top of the sash weight and fasten it to the standing part of the chain with a clip. If using a hog ring, crimp it with hog ring crimping pliers, 9 links up from end of chain.
6. Attach the chain to the sash with pig tail spring or screws. Screw the last link of the chain into the knot hole. Add another screw up from the hole an inch or two in the plough channel.
7. When the top sash is closed completely, assure the sash weight is hanging freely, 3" from the bottom of the sash weight pocket.
8. Repeat steps 5 and 6 for the lower sash.
9. When the lower sash is completely open, assure the sash weight is hanging freely, 3" from the bottom of the weight pocket.
10. Adjust sash, stops and hardware for smooth operation.

Materials:
• Sash chain, rated for weight of sashes or more
• Chain fasteners, may be supplied with chain, shaped with a hook and a pig tail spring
• Chain clips, or med-small hog rings and hog ring pliers
• Screws, small enough that they do not split open the chain links, if needed

Quality of Results:

Best Work:
Sashes slide up and down easily with chain operating smoothly through pulleys. Sash chain is securely fastened to the sash and sash weight. Sash chain weights are 3" above bottom of weight pocket.

Inadequate Work:
Chain binds in the pulleys. Weights bottom out in the sash pockets.
