MSC Multiple Seat Connector

www.strongtie.com

The MSC supports the ridge and two valleys for roof construction. Ideal for dormer roof applications.

Material: Top flange - 3 ga;
Stirrups - 7 ga for MSC4 and MSC5, 11 ga for all other sizes.

Finish: Simpson gray paint

Installation:

Distribute the total load evenly about the centerline to avoid eccentric loading.
Fasten all built-up members together as one unit.
Net height will be calculated based on specified valley member depth and slope by the factory unless noted otherwise.

Sloped And/Or Skewed Valleys:

The valley stirrups can be sloped to 45° and skewed from 25° to 45°. (MSC5 skewed 20°-45°.)
The total design load of the hanger is split between the ridge (20%) and each valley (40%).
MSC connectors can be used for two valley connections with no ridge member. Divide the total load by two for each valley load.

Valley loads are for each valley.
Other valley-ridge load distributions are allowed provided the sum of all three carried members is distributed symmetrically about the center of the hanger and combined do not exceed the total load.
MSC4 is also available in 3 1/8" Glulam width.
MSC5 is also available in widths up to 5 1/2". W2 minimum width is 3 1/8".
MSC4 is also available in widths down to 1 9/16". Use 10dx1 1/2" nails and MSC2 allowable loads.
Refer to technical bulletin T-MSC-WS for the hip valley rafter pitch conversion table.
NAILS: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long.
