The DS20-24 head and jamb seal is proved to be high performance. It is a top of the range sealing system. With rebated doors we can overpower lab tests adding the DS44. It is a high performance and economical door seal which can be installed on door stops of sufficient depth. The corner can be mitred or butt joined. 9-10 mm clearance is recommended.
Bottom drawing shows S6577 for timber joinery. Regarding double doors, refer to page 9. The DRS 1530 and DBS 1230 are fully mechanical automatic door bottoms which utilize a flat spring, which activates when the door is closed, lowering a TPE seal insert against the fl oor or threshold protruding hinge side plunger which is compressed by the frame as the door closes to activate the spring. The seal then drops in a scissors like motion from the hinge side. Use a 3mm Hex spanner to adjusting to the fl oor from a pivoting point. This motion ensures a smooth drop without drag for a tight seal, even on an uneven floor. For drop seals size, refer to page 7.
The S9168 seal is an effective and economical seal with quality self-adhesive backing, it is ideal for use on metal or timber door stops. 3 mm clearance is recommended. The DS16 Astragal, meeting stiles can be applied on one or two sides of a double door. If rebated the SV512 or S6577 seal should be used on the rebate. Fixing method zinc plated, cross recess head S.T. of the appropriate size and colour are supplied.
