Gripple® Manufacturer’s Recommendations and Important Notes
Gripple manufactures the speed clamps provided with this product. To ensure maximum safety, it is essential to follow their recommendations as listed below.
•For indoor use in a dry environment.
•Do not apply lubricant to any part of the assembly as this will alter the surface of the cable, attracting dirt and debris to adhere and possibly reducing the load capacity due to lubricant-induced slippage.
•Do not use on lifting applications; for static loads only.
•Do not use for loads outside the stated range of the product. The Gripple wedges work by using the weight of the load to draw the wedge into the cable, creating a secure grip. If used with too light a load, the wedge may not be able to securely grip the cable.
•Do not exceed the Safe Working Load (SWL) of the product. Each product is load rated and incorporates a minimum safety factor of 5:1. The SWL takes into account the specification criteria of the Gripple, the cable and the pressed ferule.
•The #2 Gripple products supplied have the suitable minimum load and the maximum SWL specifications to be used with Community’s pendant loudspeakers.
•Do not use on coated wire rope. Prior to assembly, it is essential to strip off any coating on the length of cable to be inserted into the Gripple. It is important to maintain the metal-to-metal contact between the locking wedges in the Gripple and the cable.
•When applying paint or other coating, ensure that a dedicated Gripple decor cover is used to cover the Gripple. This will ensure that the movement of the locking wedges inside the assembly is not impaired. After painting, the Gripple should not be repositioned on the cable.
•Do not use standard zinc galvanized Gripple products in chlorinated
environments. Use only Stainless Steel Gripple products in these environments. |

Hanging and Connecting the Loudspeaker
1
Before inserting cables into the Gripples, attach both snap hooks to the suspension bracket atop the loudspeaker as shown in Figure 1. The main cable attaches to the center hole, and the safety cable to either of the two outer holes depending on the desired orientation. Make sure the springloaded safety catch is positioned as shown so it closes the loop to prevent accidental detachment.
Note: Two 15-foot cable kits with Gripple Speed
Clamps are included; longer kits are available as noted under the Optional Accessories section.
Plain Cable Ends |

Snap-Hook Ends
Thread the plain ends of the main cable and safety cable up through the loudspeaker top cover as shown in Figure 2.
For clarity in Figure 3 the loudspeaker and its cover are not shown, but these should actually be in place per Figures 1 and 2. Refer to Figure 3 for the following steps:
A.Beginning with the main support cable, insert its plain end through the Gripple Speed Clamp.
Loop the cable over (or through) the ceiling anchor point, thread the plain end back through the Gripple and pull that cable end so that the loop is hanging a little lower than where you think you’ll want the loudspeaker’s attachment point to be located.
B.Repeat this with the safety cable and Gripple, looping the cable over or through an independent attachment point.
C.Support the loudspeaker with your hand at the desired height.
D.Pull the end of the main cable to take up any slack.
E.Pull the end of the safety cable to take up any slack. See Figure 6 for further height adjustments.
CAUTION: Do NOT pull the cables to raise the loudspeaker.

Insert the Euroblock plug(s) into the jack atop the loudspeaker as shown in Figure 5. No jumper is necessary because the pairs of conductors in the Euroblock jack are internally connected to pass the signal through.

Two 2-pole Euroblock plugs are supplied with the pendant loudspeaker and connect to a jack on the top of the loudspeaker as shown in Figure 4. Thread the audio cable down through the loudspeaker top cover, and then strip approximately 1/4-inch (4mm) of insulation from the cable’s inner wire conductors. Insert the wire ends into the Euroblock plug terminals using the proper polarity (marked on plugs and jack). If you daisy chain an audio cable to the next loudspeaker, bring it through the top cover as well and connect that second cable’s wire pair to the other Euroblock plug. Secure all wires by tightening the screws in the end of the Euroblock plugs.
Adjust the loudspeaker height as necessary.
A.Lift and support the loudspeaker with one hand.
B.Pull the main support cable end to take up the slack. The split cover plug is not yet pressed into position in this photo.
The Gripple Speed Clamp automatically tightens from the cable tension when you allow the loudspeaker to hang. Test by gradually lowering your hand. Don’t just “drop” the loudspeaker.
When you have the proper height set, then take up the slack on the safety cable by pulling its free end. Since the loudspeaker is already held by the main cable it isn’t necessary to support it while doing this.
